Songs from The Great Biker Build-off.....?

I heard a few nice songs from the show, The Great Biker Build-off and i really liked one of them. All i remember about the song is a kick@$$ riff from it. I know this sounds crazy but can ANYONE give me a list of the best metal songs that were featured on the show? It might be one of them....... slim chance..... but yeah, that's all i have. Thanks.
