People are different but personally I think music DOES help you focus. But only in specific conditions. Such as the music on low volume and slow. It's nice to have background noise but sometimes the background is just too good that you get distracted and put all your focus into the distraction. When you have it on low volume you will loose interest into it and just vibe with it in the background. It's also useful because is you have specific music you play while focusing, your brain will recognize the it's time to focus. I tried this and it works.
