Maybe it's just my personal experience, but I find the reverse of that is also true. If the music itself is novel, I find it much harder to focus on the task at hand.
I've got about 50 albums that I rotate through while I'm coding and I can focus on the task at hand fairly well with those on, but if I put on a new album by an artist I like, my ability to concentrate on code goes way down.
Yeah, at some point music that you are familiar with becomes background noise. I used to be able to sleep to Loveless by My Bloody Valentine at high volume. I used it to drown out other sounds when I had loud neighbors in an apartment on the bus line. When you listen to something that often, your brain just ignores it.
