The good news (depending largely upon your definition of "good") is that Aggro1 has produced a mashup of
Def Leppard vs. Goose Girl. Think Def Leppard with a touch of electro. Yes.
Also, I am loving this one: Divide and Kreate- Until it talks. Thin White Duke's remix of 'Talk' by Coldplay vs. 'Until it sleeps' by Metallica. I just played the damn song five times in a row, and it's really growing on me; I've gone from kinda liking it to loving it a bunch. Electro-pop Metallica. Who woulda guessed?
