You can also transfer the contents of your iTunes library via a flash drive or external drive, simply copy My Documents / iTunes to your external hard drive / flash drive, transfer it to your Mac, and then drag and drop the entire iTunes folder onto the iTunes icon in the dock and it will automatically import all of your songs, settings, and playlists.

There are a number of different ways to do this. If you have an external hard drive, all you need to do is drag the Macintosh HD/[your user name here]/Users/Music/iTunes folder onto the external drive, connect the external drive to your Macbook, and drag and drop the iTunes folder from the external drive onto the iTunes icon in the dock. <br /><br />If you have an iPod classic, you can do this: <br /><br />http://support.apple.com/kb/ht1329<br /><br />...or if you don't have a huge library and/or have a lot of CDs/DVDs you can use, you can back up your library to disc: <br /><br />http://support.apple.com/kb/ht1382<br /><br />...or if you have anything other other sort of iPod, iPhone, or iPad, you can rip the music from it using this utility: <br /><br />http://thelittleappfactory.com/irip/<br /><br />

hi,

Follow these steps it will help you to copy music to pc


Open iTune

confirm that your iPod is configured to enable disk use. Essentially this means that your new computer will recognize your iPod as a USB device device or a external drive.
Step2
Enable disk use if necessary. Connect your iPod to your old computer and open iTunes. When iTunes has loaded, select your iPod and display "Preferences" in the main window.
Step3
Click on the "Summary" tab and select "Manually Manage Music." You should see a check mark in the box next to "Enable Disk Use." If you don't see it, then just check that box yourself. An alert will display informing you'll now need to manually unmount the iPod as well as ejecting it in iTunes before disconnecting it from the computer.
Step4
Hit "OK" and click "Apply Preferences."
Consolidate Music
Step1
Move all your music to one place to make the transfer easier.
Step2
Navigate to the iTunes Preferences menu. In Windows, this menu is located in the Edit menu, while on a MAC it's simply it's own menu.
Step3
Go to the "Advanced" tab, then "General." Check the box next to "Copy Files to iTunes Music Folder When Adding to Library" and click "OK." iTunes will copy all of your music to the hard drive of your computer. This shouldn't be a problem unless you don't have enough disk space.
Step4
Go to the "Advanced" tab and then "Consolidate Library." Read the message that warns you that this step will place all your music in the iTunes folder and that it can't be reversed. Click "Consolidate."
Determine Storage Capacity
Step1
Make sure there's enough space on your iPod to hold the iTunes music files. In essence, you will be using your iPod as an external storage drive to bring your iTunes library to the new computer. Without a large enough storage capacity, this can't be completed.
Step2
Determine how much space is available by opening iTunes on your old computer and checking the size of the library. Click on "Music" and make note of the amount of space your library takes up. Then connect your iPod, click on it in iTunes and note the amount of free space indicated at the bottom of the pane.
Step3
Calculate to make sure that the amount of available space on your iPod is greater than the space required by the iTunes library. If not, you'll need to free up some space.
Step4
Free up space by clicking on your iPod in the Source pane and then clicking on "Music" or otherwise navigating to the contents of your iPod. Click on any song in the main library window and go to "Edit, then "Select All."
Step5
Be prepared to lose any music not contained by your iTunes library if you haven't been updating automatically, because that music isn't on your computer and will be deleted. However, if you've been updating, there's no need to worry. Press your keyboard's "Delete" button and click "Yes" when you receive the confirmation message.
Copy and Backup
Step1
Exit from iTunes and locate both your iPod and your iTunes folder. On a Mac, the iPod should be visible on the desktop and the folder is "/Users/username/Music." In Windows, the iPod is located in "My Computer" and the folder is "\Documents and Settings\username\My Documents\My Music\." Drag the folder to the iPod and wait patiently as the data transfers.
Step2
Copy your iTunes folder to your iPod. Drag the folder to the iPod and wait patiently as the data transfers. When it's done, eject the iPod from iTunes and disconnect the iPod.
Step3
. Connect your iPod to your new computer and backup any music that's in your new iTunes library. Go to "Preferences," "Advanced" then "Reset." Click "OK." Then navigate to "Advanced," "Consolidate Library" and click "Consolidate."
Step4
Copy your music to your new computer. Locate the Music folder on your new computer--it will have the same name as on the old computer--and drag the iTunes folder from it to the desktop. Find your iPod, double-click to open it and drag the iTunes folder copied from your old computer to the new computer's iTunes folder.
Step5
Wait as the music is copied to the folder and then open iTunes. The music and all of its accompanying information should sync without problem.

You can actually (or could have) transfer the songs from your
Laptop & iPod by using you iPod like a removable
Hard Disk Drive

Here is the Apple sanctioned method:

Note: While you can use the Transfer Purchase From iPod option under the File menu to copy iTunes Store purchases from the iPod to another computer you can't transfer songs from other sources from the iPod library to iTunes

So you'll need to follow the steps below to use iPod as a hard disk to transfer music files from one computer to another. This process will require the use of iTunes 7 on all computers. Any computers running iTunes 6 or earlier will need to be updated to follow these steps.

Once you have the files transferred, you'll need to authorize any iTunes Store content. If you won't be using your old computer, you'll want to deauthorize it.

Important: Windows operating systems don't recognize Mac OS-formatted disks (HFS or HFS Plus formats), so you can't use a Mac-formatted iPod to move your music to a Windows PC.
Switch the iPod to manual update and enable disk use The first thing you need to do is make sure have configured your iPod to enable disk use. To do this:

1. Open iTunes on your old computer.
2. Connect your iPod to your old computer and wait for it to appear in iTunes.
3. Select your iPod in the Source pane under the Devices section to display your iPod preferences in the main library window.
4. Click the Summary tab in the main iTunes window.
5. Click the Manually manage music button. Changing from automatic updating to manual puts a check mark by Enable disk use. A message says:

"Disabling automatic update requires manually unmounting the iPod before each disconnect."




If you need to copy from old computer:
Copy iTunes folder to iPod To copy all your music files (including the library file that holds all your playlists and other settings) to your iPod:

1. Quit iTunes.
2. Locate your iPod:
   Mac OS X: On the desktop
   Windows: In My Computer
3. Locate your iTunes folder:
   Mac OS X: /Users/username/Music
   Windows: \Documents and Settings\username\My Documents\My Music\
4. Drag the iTunes folder to the iPod. This can take a while if you have a lot of songs.

OR

• When the copy completes open iTunes.

• Click on the iPod in the Source pane

• Click the Eject button in the lower right corner of the iTunes window.

• Disconnect the iPod from the computer when the "Do not disconnect" message no longer appears on the iPod screen.

Now:
Copy music to new computer To copy all your music files (including the library file that holds all your playlists and other settings) to your new computer:

1. Locate your Music folder (Mac OS X) or your My Music folder (Windows) on your new computer:
   Mac OS X: /Users/username/Music
   Windows: \Documents and Settings\username\My Documents\My Music\
2. Drag the iTunes folder in this location out to the desktop. From the My Music folder to the Desktop on your new PC
   

• Locate the iPod on the new computer:
  
• Mac OS X: On the desktop.
  
• Windows: In My Computer.
  
• Double-click on the iPod to open it.
  
• Drag the iTunes folder from the iPod to the Music folder (Mac OS X) or My Music Folder (Windows) on your new computer. This can take a while if you have a lot of songs.
  
• Open iTunes
  There you go. All your music, playlists, and other information like play counts and ratings have all been moved from your old computer to your new one.
  

If that doesn't cover it fully..... wow!

If you have an Exclamation mark next to the song, it means the computer cannot locate the song. Remember that Itunes is only a player, and the music is not there. It should be kept in your music folder. If you go to ADVANCED and select consolidate library, all mp3s or itunes playable audio will be consolidated. You then want to go to preferences, and reset your music folder location. If you still cannot locate the music, theyve either been deleted or have gone corrupted.


Hope this helps.
