I'm having issues with one of my older MP3 players, Creative Muvo V100. I've downloaded over 200 songs onto it but it will only play 24. When plugged into my desktop it shows over 200 songs but I can't get it to play all of them. Been dealing with this issue for about a year now. I've done all the updates available and used numerous different music programs but no joy. I would just throw it away but it's been the easiest mp3 to operate on the bike with gloves and the battery lasts for weeks.
