Showing my age.....Led Zeppelin, even though most of their stuff ripped off genuine delta bluesmen they were still pretty kick ass in their time.

Current fav: Incubus, White Stripes, Coldplay when im feelin mellow. (which is rare)

Oh, and Offspring is perhaps the least talented band of the last decade. Mindless dribble targeted to a 12-14 yr old audience.
