Yes, converting AUDIO files might have a lot to deal with the sound, the Sansa Clip Jam, supports MP3 and WMA files with no problem.
My best solution for you, is to use a reliable audio converter, for example you can use Xilisoft audio converter, I personaly use both versions audio and video, and they work great, the only con I could see, is the timing adjustment of the cutting (it may cut 1-3 seconds of the end of the file) in case you’d like to cut some intro or the end, but since you know this trick you will manage to play it around.
Good luck BuddyHollyJR
