I have the music turned off, note blocks and jukeboxes on 100% and A few things on a low rate, to kind of give the feeling of the game. I mainly play creative nowdays, so things like hostile mobs aren't needed for me. I also just find my own music ways better for what I do, I mean, I usually get my inspiration from my music, and minecraft music isn't the most inspiering... Well, I can get why you like the soundstrack, I mean, the songs aren't terrible, but, you're playing occasionally. I, for example, sometimes build for over eight hours straigt, I can tell you, the two/three different songs do get annoing then... really... I also had the music on back in the days I played half an hour a day at most, But it just is annoing when you play a lot.
There are plenty of songs nowadays, I think, not just two or three. But many might only play in more specific circumstances, I'm not sure.
