I applaud your friend. In fact, if I were you (and your friend was a girl), I would attempt to marry your friend.
See, a long, long time ago (December, when I bought the computer), I put everything I had on Media Player. Rare videos, live videos, live song acoustic versions, and etc - they made up most of my home life when I wasn't living with my girlfriend. In any case, last month (though it might have been this month), I went to play some songs, and it didn't load, which isn't an uncommon problem. I closed it, opened it again, and bam - everything was gone. All songs, all playlists, all lyrics (and I had the full correct lyrics to all 350 songs plus the videos). Everything was gone. Everything. Everything. Everything. And, for effect, everything. I've resorted to Music Match (MusicMatch!) even though it refuses to play videos. My life was destroyed. I hate Media Player. I now wish it would die. And I would just let it rot, too.
So what's the moral?
MEDIA PLAYER SUCKS, IF I EVER CATCH YOU USING IT.... ..... .... YOU DON'T WANT ME TO FINISH THAT SENTENCE.
