i used to do this constantly. but back then, music was the most important thing in my life.
so when all my old favorites sounded stale, i'd dive into another genre.
now, when i'm bored with music, i'll do other things.
i have a pretty set palate. i'll discover new stuff, but i don't make it a point to go too far outside of stuff i already kinda have an ear for.
someone above me said "heard it all before." i don't think that's really the case for me, but i have heard a shitload of different types of music, and i don't go out of my way to broaden my palate anymore.
