When reading or studying no I don't because I find it distracting. If I am doing my writing I like to, as it gets the creative juices flowing. Funny how some things you can have music, but others you can't.
I enjoy music but don't have it on when I am concentrating. I like music when I am driving and doing housework.
I like to hear environmental sounds so find music makes them hard to hear. I think that came about from being a solo parent and needing to listen out for my son and impending danger, I guess.
