Trouble dowloading (any) music
 

When I attempt to download music, none of the songs work, well maybe 5 out of the at least 100+ I have tried.
When I double click to download a song, the song will start to download, but when I preview the song....
1) Music does not play, and I have tried well over 100 songs,
2) The preview says the song is anywhere from 16 to 44 minutes long, when I know for a fact the song should be 4 or 5 min.

I have this same issue with other p2p networks, so I wasnt sure if it was my computer or not, I dont see anything wrong with it.
None of my friends know what to tell me, they use this and theirs works fine,
any help would be appreciated, thanks.

Edit: This has nothing to do with corrupt files, as 98% of the songs can successfully download.
