When I was in high school, my math teacher would play Mozart during tests, claiming it would help us. It would drive me crazy, and I doubt that my grades improved as a result of the distraction.
For what it's worth, I have a BMus in Piano Performance. I love music... but never as "background noise"!
Before this, I could not listen to music and code at the same time AT ALL. Then, I found a coding playlist with only full length albums with very little vocals, and I changed. I recently created my own flavor of the playlist with only albums that have a consistent flow from one song to the next.
Give it a try and fork it to make your own version!
