Typically a big fan of internet radio when I find it. There are a few good/free ones out there. 1.fm is fine. It's like traditional internet radio though with some ads and songs that repeat every 30 mins or so. Navidrome and other subsonic servers allow you to save these stations and stream them from your browser or compatible clients. Spotify has basically blocked my penitently and i refuse to install their apps to spy on me, when I pay them and used to be able to use a web browser.
