So I've been enjoying listening to different radio stations all over the world for the past month and have never felt the need to open Spotify. Might be cancelling my subscription soon. It's also pretty cool to listen to a radio program that's been hand picked by a radio host. Of course that doesn't count if you're an audiophile that needs the best quality, or really want to pick every single song yourself, but for me it's more than good enough. radio.garden has a pretty fun way to discover internet radio stations with an interactive globe you can spin around in your web browser or in app.
Yep. I was about to recommend Soma.fm too when I saw your comment. Groove Salad, Deep Space One, and Space Station are my favorites on there right now. I discover great new artists from Soma all the time, like Rei Harakami, who I've been obsessed with lately. HIGHLY recommended.
