I discussed this with a friend pretty recently. I wondered whether I was getting "older" because I couldn't find anything I liked about the current rappy-pop or soft, high-pitched chic-pop that you hear over loudspeakers at the grocery store, gym, etc. It's grating to listen to, majority of the stuff I can't even determine what the melody is supposed to be.
Then I realized that I'm listening to new alt/indie stuff that I didn't know about three years ago, and that it's probably not me. It's probably just that this mass-music for the masses is indeed awful.
