My current favorites are probably Gorillaz, System of a Down, and Green Day. I like Green Day for when I need to get out some Teen Angst™, Gorillaz was one of the first bands I ever got into and has always been a favorite band among my family (I might even be going to a Gorillaz concert later this year!), and I just love System of a Down's variety of songs---tbh, they don't have a single song I actually dislike. I'm not too adventurous when it comes to music, I pretty much listen exclusively to the few bands I like and rarely actually venture out into new music.
