Back in 2006 I took the cover that BifN aked did of Nothing Else Matters, got her voice and matched it up to Metallica to make a kind of "duet" of the song. It's a bit sloppy in places but for the 1st attempt at anything like this, I think it aint bad at all. All I used was Audacity () and Virtual DJ (www.virtualdj.com) Comments Welcome.
