When I'm outside in my work room, I listen to the radio or my library of music on my Ipod. Old School Reggae for me too:
Steel Pulse (the early stuff: Tribute to the Martyrs, Handsworth), All of Bob's stuff, Third World (the early stuff), Jacob "Killer" Miller (and the Inner Circle), Black Uhuru, Culture, Burning Spear, Dillinger, et al.
Jazz:
Boney James, Euge Groove, Earl Klugh, Najee, Paul Taylor, Fourplay (no, not the action, but the group), Joe Sample, Hiroshima, Norman Brown, Mindi Abair (man she is hot), Spyro Gyra, The Rippingtons, et al.
Then there's old school R&B and Soul (Isley Brothers, Ojays, Frankie Beverly and Maze, Marvin Gay, Stevie Wonder and Earth, Wind & Fire: EWF has some pretty interesting album covers too).
And on Sunday mornings, Gospel.
