All bands that I've loved for a long time now that still get me tingling whenever I hear them or if there's any new releases by them. I used to have many more "favorite" bands from years past (Guns 'N Roses, Mötley Crüe to name a few) whom I still enjoy listening to from time to time but either the spark has gone or the novelty had worn off that I'm past caring what these bands do with themselves anymore. Plus (and I'm sorry to admit to myself) I think I'm just not as into music as I used to be.
