Depends,
David Bowie can be ill on really deep days.
But generally I ride to a Mix of Dancehall and hip-hop.
(I.e Turbulence, e-40, Mac Dre, Nas, Damien Marley, Sizzla, King Geedorah, Ghostface)
Don't forget those mashups either
Scope "night Ripper" by Girl Talk. That's like one entire album of riding soundtrack. Super flow too.
