Generally EDM. It's hard because you have to keep finding new tracks. EDM songs don't age well. They get your blood pumping the first few times you hear them, but after that they're pretty boring.
Genuinely interesting songs are bad for my chess, because I start listening to them during the game... so I like to have a somewhat simple song with a strong beat... thus EDM.
But sometimes guitar stuff too like Polyphia or Angel Vivaldi.
