I'm 64 and got very interested in music which was called punk or new wave. I played in some bands. I love indie rock/dream pop etc. I am constantly on the lookout for new music and sometimes it is older stuff I had never heard of before.
I've almost never listened to music which most people like and that is true going back to the mid-1970s. So far this year I've found releases by Alex G, Nova Twins, Soccer Mommy, Jadu Heart, older stuff by the Throwing Muses, Beach House and others. I really enjoy listening to Alvvays (3 albums so far), Pip Blom, MIYNT and others.
I do think that listening to new types of music requires your brain to adapt (actually changing the brain waves) and, nowadays, if a song doesn't hook you within a couple of bars, people ignore it. I do listen to and like almost all genres including classical, jazz (listening to Dave Brubreck right now), classic rock, rap, singer songwriter, bluegrass, etc.
