Do you live near a city? Because pretty much every major city has a few. KEXP, WPFW, WUSC, KNHC are all local stations playing interesting non top 40 music that have been operating for decades in places that I have lived. Dublab & The Lot radio are also really good over the internet.

If there are non around you just pick a random place in the world here and listen: https://radio.garden

It's certainly 100x better than corporate and/or AI slop streams
