To be honest, music doesn't help everyone, like for example I tried to listen to music during my tournament matches and I played exponentially worse since my body was trying to play to the rhythm of the song instead of focusing on the game, I found it very distracting. I felt awesome while playing yeah but I was playing terribly. Music only helps some people get in the zone and play better, the thing that gets people in the zone is unique to everyone. Sometimes it's music, sometimes its talking, sometimes its meditation, sometimes it's getting angry, sometimes it is being hungry or full etc. Etc.
