Just about any kind of music.
I mean, I have my favorites. I really like Blues. I like some jazz...and then bits and pieces of every other genre.
If I gotta listen to rap, please make it old school ... and I don't like being screamed at.
I'll listen to something at least once.
I've got certain CD's I play when I'm writing. There's CD's specially crafted for driving. Then there are the Sing along songs. Also good for driving and embarrassing the children.
Then there's Queen.
They fit in so many categories. If I were to make a mix CD for kitchen/car/writing - there'd be at least one song of theirs on the CD. I can guarantee it.
