I think I stopped actively seeking out new music maybe a decade ago. That's not to say I don't listen to it on the radio, I don't listen exclusively to 'old fart' music channels! I'm just not as active as I once was.
These days, I like to discover stuff I've missed out on due to my past earnest desire to stay 'finger on the pulse' That does, ironically, lead to me listening to what you might call old fart music sometimes but not singularly so, and certainly not headline acts, more the influencers of headline acts - if I can put it like that.
For example, I was reading about The Charlatans yesterday, and they cited a range of influences. I would follow up on those influences these days. Or, I liked a description of them sounding like "the Spencer Davis Group on acid", so that might make me want to listen to them.
