My best advice would be to branch out. Listen to other genres that you might not have listened to before. I say you should definitely check out some Prog bands like Devin Townsend, Porcupine Tree, Flower Kings, and Transatlantic. Also, never listen to just one genre. Try to keep it interesting and jump around. One thing that sucks when it comes to music and being burned out on different bands, at least for me. I say you should go to YouTube and search up and listen to the full album of Devin Townsend's Ziltoid the Omnicient or Deconstruction if you want to listen to something a little more heavy. Or whatever. I hope you don't give up on music just yet! There's always good listenin' out there.
