Before I am about to play chess OTB, I try to enter a certain mental state where I am completely focused on chess, not thinking about other things (work, etc.). In my opinion, this is very important, since more games are lost due to oversights caused by a general lack of focus rather than ability and/or opening prep. In other words, regardless of your skill, you ought to be prepared to give 100% at the board.

To do so, I usually listen to some music before the game. (about half an hour, let's say) - so I was wondering if other people share the same habit :) (and if so, what are you listening to?)

Which sort of music - well it depends on my mood on that day, but usually something like this:

 Aargh, listening to that's more likely to make we want to jump off the balcony, lol

I like the Ecstacy of Gold to get myself in the state of mind for the battle to come:

That's also a good one, I agree :)

btw, there is also this version:

Classical Music only, probably Bach or Mozart.

Or opera :)

Ah yes that is a good version too, but I need a powerful soprano

Yep, classical music is great.

Though I usually prefer something epic with a modern twist. Like:
