I'd like to shout out community radio as well! Your town or city probably has one or you can stream them online. Local DJs playing whatever they want with no ads, just music. I volunteer for a couple and they're really fun to be a part of.
When I was at uni in the early 2000s in the UK our uni radio was internet only. I would assume that's something that wouldn't have gone backwards in the last 20 or so years.
