I just picked up a cell phone that doubles as an mp3 player and was thinking about using it and headphones during practice. I've read a lot about how some people like the least amount of distractions possible, such as shooting at tables away from crowds or windows, asking to have the room music or tv turned down low, etc. etc. Do you think this detracts from building up your ability to ignore such distractions or do you think the added focus on your game is a better trade off? Do you also think that by practicing with music, you'll need music to be able to feel comfortable shooting if you get used to it?
