With all due respect, you don't need to spout out random posts as son as you join a forum. It's usually best to watch the forums and join other posts for a bit to see what's been done and what hasn't.
In answer to your question, I don't have a single favourite because I have favourite songs from different bands. Assemblage 23 is the band with the most songs which I like so if I had to single it down then I guess I'd say them.
