Because things have to be catagorized and organized.

If it was your way, going into a store to buy a CD would be impossible to find anything.

Going into a library the same way. My wife does all of the CD buying for our local library. She studies the music hard to fit a category. Without it, you would be able to find nothing.

don't be so concerned. Just take your own advice and enjoy the music, whatever it's called.
