Everything. Literally. I was a Classic Rock reader for a long time.
Despite being unable to play instruments myself, I get on better with those who are musically inclined, or at least interested in it, than those who aren't. Which isn't to say I wouldn't bother talking to those who are/were neither – it'd just be 10x easier to have a conversation with those who are. & forget being in a relationship with someone uninterested!
Nearly all my male relatives are/have been into their music, & – it's been the basis, as well as the end of in some cases – most of my friendships. If you're interested enough there's a song for every situation. Songs can – & do -- take pain away (both physical & mental) get anger out, depress me, warn me, cheer me up.
One of the few things I like about my various living arrangements is they're usually comprised of lots of old rockers – sadly this place is one of the very few exceptions.
