I downloaded them from a site
usually it works, but recently my mp3 player has been acting funny doing this problem so I reformatted it and I thought it was doing fine (for about two weeks) then I added some music and it started acting funny again
Again, you’re being too vague for anyone to realistically help you. Is this a legal site, or some file-stealing/sharing site like limewire or some other illegal torrent?
If it’s a legitimate site, there’s always the possibility that something happened during the download (however, that possibility is very remote), but if it’s a questionable (read: illegal) site then you never know what you’re going to get.
