I'm usually coding while listening to Drum and Bass. But for example, today I've been listening to Stax (Soul/Funk). Other days I'm listening to Punk, Ska, Reggae, Hip-Hop [...] At least twice a week I listen to roots Blue music!

It's up to you, I don't think there's such thing as "music" made for programming, if so, I would say late night and silence...really...!
