Younger people of Lemmy. Would you buy a CD at a concert?

I'm 40, and when I was a teenager, EVERY band had CDs. And I know a lot of music has shifted to digital. So much so that I heard Best buy stopped selling CDs. Presumably because nobody buys them.

So I wonder what musicians sell besides t-shirts and posters at concerts. Do the kids have ANY CDs? Do they buy mp3's? Do they just use pandora and spotify? Do they even own their own music?

I've given up on trying to understand the lingo. Other generations lingo sounds stupid to me, but still understandable based on context.

I have NO idea what a skibifibi toilet is....sounds like a toilet after some taco bell and untalented jazz, but maybe I can try to understand their thought process on media consumption.
