What do you listen to when you write?

There are many bands that are special to me, but they're not linked with my writing. Sometimes I listen to music when I write, sometimes not. Sometimes it's my choice, sometimes it's my partner's. Sometimes he'll be watching tv or we'll be listening to Radio 4. Sometimes I'll be writing in a cafe so whatever they're playing is what I can hear. I love music, but I don't use it to help me write.
