It doesn't have to be Richter or Bach, you can put both, one in performer and the other in composer. At least that's what I do. I don't know if you can do that with iTunes or WMP (which I recommend you uninstall) but I use Media Monkey, Google it, it's the best there is for sorting music. You can use tags and see your music sorted by performer, composer, album, genre, year, etc. etc. etc. You can even track down files that changed directory (but only with the gold version). Sounds like I'm advertising but really, I have a big library and I have no amazing dilemmas about organizing it so far.
