Basically, random songs I download decide not to play. I only download mp3's over 2000 kb and i heard about that worm going around, so i checked out my songs to make sure they didnt change to exe's and they didnt. but the funny thing is when I go to delete them, it says I cannot because they are in use by another application. Only application i have open is limewire and the songs aren't playing. All help is appreciated.
