Comment 9 for bug 3668

I have had this same problem.. and it seems to be an issue with corrupt MP3 files.

I was downloading some from bit torrent, and it was one of the songs said it was finished, but had the problem you had. I re-opened the torrent file and the hash check found something corrupt and started to re-download the parts, and it was fine.

MP3 is MP3 after all.
