Increasingly I can't get into new music. For a while, I couldn't understand why as I've been a rabid musician / music lover my entire life. Even music I thought was cool, I couldn't really get into. I always preferred the music I grew up with.
Eventually, the reason why became obvious. I grew up listening to all that music with my closest friends. It's the memories I associate with that music that keeps me coming back. I moved away 30 years ago and never established friendships like that again. New music feels hollow to me because I don't have buddies to share it with and build associated memories.
