I think the logical conclusion here is to not wate our times with music before late Beethoven and after death of Wagner. Maybe make exceptions for Bach and Scriabin, but that's it. And micro-composers (as I like to call them) like Mozart and Mahler for a snack every now and then (but not too much, lacks nutrients).
