Very rarely I use custom-filtered (brownish) noise to help with isolation. Perhaps some kind of Ambient or New Age would work too in such situations, but things I like in those genres require attention and not paying it would be absolutely disrespectful.
I listen to all kinds of music at my dayjob but only during specific activities that do not require much contemplation and I can mostly flow with the music and do the work in the background.
Though, I'm a musician and sound engineer, so my relationships with music in general might be a bit special.
