My mum also loves music still, though sadly most of her enthusiasm is on Ed Sheeran these days.
I still try to listen to new releases as much as possible and limit listening to older stuff. I think I’m safe from only listening to my ‘era’ of music because fuck me, so much of what I listened to between 1999 - 2006 was absolute guff. Nu metal, britrock, landfill indie and post-punk pastiche haircut bands. 
I’d like to go to more gigs, I’ve hardly been to any the past few years - ironically moving in with two of my ATDs meant we went out way less than when we’d hang out at shows.
