No music for me. You get accustomed to a certain routine when dealing with competitive events. When things remind you of that routine it puts you in that mental context, like getting pumped up or putting your game face on or whatever you call it. If I started trying the musical approach, then it would become habit and I like to be able to gear up for shiai and gradings in a serious fashion without the need for any outside motivation. And I may sound like an old man, but when I see people warming up for shiai and stuff with ipods on, it just doesn't look right to me. Kendo is more than a sport or a game and the musical approach reminds me of that. Although yes, shiai is still just a sport and a game as well. Hopefully you know what I mean so let's not go there.
