Won't play some songs

When I plug it into the computer it shows that I have way more songs on there then actually play. If I just have it on regular play it only shows a choice of about 80 some songs, and I know there is about 120 some. I can listen to them if I go and select just that song from the navigator and look at all the music i have, but it will only have the one song selected and I will have to go select a new song after each one. Is there a way to show all of them all at once?

SOURCE: My coby mp 610 wont play all the music i have on it.

I use a different MP3 player, but I noticed that mine wouldn't play .AAC files, only .MP3 files. I upgraded the firmware of mine and then it played everything. I noticed there is a new firmware upgrade for the COBY 610, so that might be of help to you.

You can find it at the website by choosing 'Mp3 & Portable', then 'Mp3 & Mp4 Players', then your model 'MP610', from the support page. Or, here is the direct link to the file from Coby's servers.


Unpacking the zipfile from the Coby Website will give you a PDF file with instructions, and a program file to run.

Your music will be erased when you run this firmware update. The instructions suggest that even if your mp3 player won't startup properly, if you plug it into your computer you should be able to access it as a removable disk, and copy all your music to a temporary folder on your computer.

Here are the steps:

  1. Plug your MP610 into your computer.
  2. Copy all your music to a temporary folder.
  3. Disconnect your MP610 from your computer.
  4. Disconnect as many USB devices as possible from your computer (to simplify identifying the MP610 at a later step, and avoid damaging other devices by trying to load the MP610 firmware into them by mistake.)
  5. Run the Firmware Update program 'MP610 T LCD Firmware Update for file sys err.exe'
  6. You will see a screen with up to 24 numbered, empty boxes.
  7. Connect the MP610 to your computer. It will show up in one of the boxes.
  8. Once the MP3 player shows up, click on the Firmware Feature icon to start the firmware upgrade.
  9. After the firmware update is complete, you will receive a checkmark in the Firmware box.
  10. Disconnect the MP610.
  11. Close the firmware update software.
  12. Turn on the 610 to confirm it starts up and the display reads 'COBY'.
  13. Plug it back into your computer and copy your music back on to it.


I hope that helps.

Machspeed Eclipse 180v 4GB not showing all files

The problem is that you might have unplugged your device, before all of your songs could sync onto your device. Try plugging your device back up to your computer and sync the songs on there that isnt already on your device.

Cant play back tracks no data

Did you add songs to it yet? To add songs to it plug it in the your computer and import the songs to it. If it still won`t work rebuild your data base. Doing so well factory reset your Walkman and fix any bugs in your Walkman.

Video songs

this is because your mp3 player isn't meant to play video songs. its an MP3 player, meaning it won''t play AVI video files.

Am unable delete song...they do not show up on my computer either

I have a dffierent mp3 player Colby with a usb and I had the same problem. Try deleting the songs from the device itself. If you go into folder view if you havet hat option and choose the song it says to play or delet, at least that is what mine says. It may take awhile to do it one song at a time, but you should have the option of deleting the songs from the actual mp3 player.

I also had minenot show up, mine was do to deleting some of the software off of the player to make more room for songs. I never used podcasts and other files that came on it, so after I deleted them my songs stopped showing up. I just copy the songs to my mp3 player now, and delete them one by one. Hope this helps you.

The players starts playing and then says file error

If this is a USB MP3 player and you have unwanted songs on it, you might try plugging it into your computer and formatting it like a portable hard drive. This should reset everything back to a factory default and then the computer and the MP3 player should get along better. Good Luck

Song's won't load, even though the files show

Yeah, the songs are in the wrong format for your player.There are some DRM-protected songs that allow you to play the song on your computer, but they won't actually play on an mp3 player even though they appear to transfer. If you download ALL of your songs in mp3 format, you will never have this problem.

I've downloaded songs but they don't show up on my player

Each mp3 player can only play songs in certain formats. A Philips GoGear, for instance, can't read iTunes format. Some players cannot read DRM-encrypted WMA files, which is what most music services use. When you load a song in the wrong format to an mp3 player, the song appears to transfer, but the mp3 player won't actually play it. The best workaround for this problem is to only load songs that are in true mp3 format - they are accepted by 99% of digital audio players. If you give us your manufacvturer/model #, and music service name, we can tell you exactly which formats your player plays.

Shows there are no files

Actually, you do not have the same problem - random deletion is caused by DB corruption, and can be solved by updating the player's firmware at

Vhart - The songs are in the wrong format - it does not recognize iTunes songs or DRM-encrypted songs which do not have "transfer rights" (many msuic services - especially free ones but also paid ones - give you WMA's that have "play rights" -i.e. you can play them on your computer; but if they do not have transfer rights, they will show up in your player, yet not play correctly/skip).

Transfer only songs that are in Mp3 Format and you will never have this problem.

Shows songs, but doesnt play them

Have you tried holding the select (center) and menu buttons together? This will completely reset your iPod to its factory settings, whereupon you can plug it into your computer and sync your songs back.

I'd recommend restoring the firmware to the latest version as well, even if you had the most current version installed, as this will usually aid with these kinds of software-induced problems.
