Personally, I find it much easier to concentrate when I have classical music to listen to when playing chess. If I was playing any other song, it brings the worst out of me and I make bad moves. Anyone out there with similar circumstances?

For my music list, I enjoy listening to something sad. Right now, I'm loving "Song from a Secret Garden" and "When it rains" and "Kiss the rain".

I like space music especially Steve Roach's Structures from Silence.  Modern classical is great like Steve Reich but I wouldn't listen to it during a chess game because it tends to steal my attention.

I always listen to music when playing online. I'll listen to pretty much anything.

Classical music (and jazz) are too distracting for me, they demand your full attention. I usually listen to AC/DC or ZZ Top while playing.

Chopin Nocturne Op.9 No.2

music  improves my game, especially chill out music

I listen to almost anything, but mostly classical and metal. (Two very different genres, but they help me focus.)
