I think that depends of your concentration level, personally i like to play with no music at live games, but online u dont have to worry about opponents tells, so listen some kind of music doesnt affect my game.
I think there are pros and cons to listening to music. If you're playing online I'd say it's all cons, but at a live table, it seems like the headphones would be either intimidating (people think you don't need to pay as much attention) or give you more calls (people think you "aren't" paying enough attention). In the end I don't think it matters too much. For the people obsessed with their ipods enough to wear them in tournaments, I think without them they'd still have music playing in their head.
I like to play to music sometimes, but I seem to do better when it is off.. The more mellow the music the better I do.. I think if the music is too fast them I tend to rush plays and make haste decisions because I'm focusing on the music instead of the poker.
drugs can give yu supernatural powers too . they can give you supernatural powers because when you are on them can you really tell yourself you don't have supernatural powers?? drugs with trance music though, you're superman resurrected.i think its better to listen to music... i like it because it puts me into a crazy zone sometimes and it feels like i got supernatural powers ... but it has to be trance music of course...
Think what the question should be is "do you listen to music AND win money at cards? Its ok saying you either do or don't but makes no differance if your a losing player?
Am I talking sense?
for the record I play most of my poker in my underwear, so playing live could get me strange looks so I just play on-line.
