there are tastes for a reason

Just heard a stream host on RadioIO80s advertise her new show. I listen to RadioIO80s for hours every day, as if just waiting to hear "Getting Away With It" by Electronic. But that's neither here nor there. This Mary McCann advertised her show, Great Music--I think it's called--as being a collection of great songs from all genres and eras. I thought, "If you like everything, you like nothing." I can't stand people whose tastes are so wide-ranging. Can they not be loyal? Plus, she identified herself as a life-long music freak. As if you're the only one, hon.
