Mostly no music at all.

If I listen to music, then it's mostly classics like sonatas by Bach, Beethoven, Chopin or Mozart. And it's always music that I know very well, so that it doesn't draw away my attention. For the same reason it's mostly music with very few instruments. You can't concentrate on coding and a fully orchestrated symphony the same time. Jazz is another option. Again: Shouldn't be too complex. More like solo instrument. Keith Jarret playing piano is a good example.

Less likely other modern music. Singing I experience as distracting. Unless I don't know the language, so that I'm not tempted to follow it, Jan Garbarek playing sax together with the Hilliard Ensemble singing in Latin works great.

Though I listen to a lot of different music when I'm not coding.
