BD, RE:Rite of Spring. People I know really, really hated the show, but man when they come in with the main theme of Rite of Spring I just can't get enough. Constantly listen to that show.
Madison '15 was one that I really harbor a special spot for as well. Not sure how everyone else took it, haven't seen anything much about it in writing or otherwise, but it's probably one of the most catchy shows out there. I love the groove.
