Reggae- Gregory Isaacs, Bob Marley, Sugar Minott, Beres Hammond, Jimmy Cliff, Dennis Brown, Yellowman, The Mighty Diamonds, Lucky Dube, Alpha Blondy, etc...mostly roots that dancehall annoys me.
Ol School- Smokey Robinson, Marvin Gaye, The Isleys, James Brown, Funkadelic, Rufus and Chaka Khan, Rick James (pre-bondage days), Stevie Wonder, Aretha Franklin, The Barkays, Heatwave, etc.
R&B- D'angelo, Rafael Saadiq, Angie Stone, Jill Scott, R Kelly (haha), Tone Toni Tony, etc.
Even Disco- Bee Gees, KC and the Sunshine Band, Dr. Hook, The Hughes Corp., whatever sounds cool.
