the music when playing poker is very stimulating .. in poker as in any therapy .. in my case it is according to the tournament step of heavy metal classical music and even the very same daddy yanke
When I started playing, some years ago, I used to listen to my favorites songs. Now I listen to some calm music, meditation music until the end of tournaments, at the end I change to agressive music.
Very interesting question.
I just cannot play online poker without music. Music keeps me alive and so i can grind more than 5hours. I literally listen to music every time i play poker. Its not distracting for me at all. I like music while playing, because it clears my mind so i can focus on the game.
