It depends on my mood. If I'm in an agressive mood and want to really burn it up I excercise to Dr. Dre's Chronic and Nativity in Black-Tribute to Black Sabbath. If I'm in a good upbeat energetic mood I like Janet Jackson's last cd, Snoop, or Tu Pac. If I'm feeling nostalic and like visiting some old friends I listen to some real good Motown, James Brown, Marvin Gaye, Aretha, Glady's, Sly & the Family Stone...so many good ones. I always add some mellow ones at the end for stretching. Usually it's something instumental and acoustic. This is the current favorites..I'm probably going to mix it up soon.
