day listening to music. I'm not a big music guy to begin with. I never even turn on the radio in my car, so 4 hours of music daily seems like torture to me.

I'm certain you will tell me you "just have it on in the background", but I'm going to be the debbie downer and point out that multi-tasking is a myth. Your brain doesn't multi-task, it switches between them. It's a process referred to as task-switching and it lowers productivity, reduces work quality, and increases errors by up to 40%.
