I love music, but I've never been able to work while listening to music. If it's music I enjoy, it consumes my attention (see quote below), especially if I'm familiar with the specific songs. I don't like listening to music on "broadcast," so I'll almost never enjoy a Pandora station even of a genre I generally enjoy.

"Music is the pleasure the human soul experiences from counting without being aware that it is counting." -Gottfried Leibniz
