Cant delete songs off my ipod
Two possible solutions:
Solution 1. Go to iTunes, go to Edit, Select All, go to Edit once again, select Delete. This will clear your whole music library. Connect you iPod and let it sync. It will delete everything in your iPod. The problem with this is that it will delete all your music in iTunes as well so you better back it up elsewhere.
Solution 2. Go to iTunes, connect your iPod, let it sync. Do not disconnect your iPod. On the left hand side of the screen you will see "Library", "Store", "Devices", etc. Go to "Devices" and you will see your iPod's name there. Click on it and you will see on the right hand side of your screen your iPod, with some menus tabs. On the first tab (Summary), make sure that "Sync only checked songs" is activated. Then go to the second tab ("Music"). Make sure "Sync music" is activated and "Selected playlists" is also activated. Make sure NONE of the playlists is activated. At the bottom right hand side of the scree there is a button that says "Sync". Press it and it will sync no songs into your iPod. That should clear the songs but leave the contents in iTunes intact. If you want to put some playlists in your iPod, then check only those and only those will be added to your iPod.
Hope this helps.
