It totally depends upon what I'm doing. On the treadmill, it's all about the Rolling Stones, although I also have a few others. For cleaning the bathroom, it's GOT to be the Supremes. I have a collection of the best of the Supremes, and I CANNOT clean the bathroom unless it's on. I'm a total sucker for anything from Motown. My favorites are probably Marvin Gaye and Smokey Robinson. When it comes to music, I'm a real geezer.
