Depends. For some players it relaxes them or takes away their sense of outside sound in a way that seemingly hones their remaining senses. For me I prefer no music. I would probably just find it distracting in a live
poker game. I am too focused on many other things: live
tells, changing stack sizes and blinds, calculating math in my head like pot
odds and so on. I am already not the best at math, so I don't need further distractions lol
Ironically, playing online, I am far more likely to listen to some music. Maybe it is because I have less to worry about (like no need to look for physical tells or estimate chip stacks since online displays exact amounts). When I am listening to music online, it is usually more background music to keep me motivated; I normally enjoy classical music or other "relaxing" choices, but for some reason I don't think I would care for that during poker.
When playing poker I'd probably listen to something like John Cameron 4 O'clock Rumble (
wsop Main Event Theme Song), or Motorhead Ace of Spades or something else upbeat and motivational for poker
