Usually, I get this problem when trying to download mp4 songs onto my Sansa Clip. The songs will transfer, but the it skips and fuzzes and distorts the song to where its unlistenable. Generally, my Sansa Clip will skip the song after a few seconds or a third into it if I really push it.
But since I’ve purchased a new laptop (Asus, with windows 8) all .mp3 songs are giving me this problem. No clue what to do about it.
