I'm a big fan of Chile based Radio Isla Negra (available in Slow beat and upbeat as well as the regular eclectic selection on a well curated playlist.) No Ads, No DJs, just an occasional jingle. Much of it is just "new to me" rather than strictly "new", but it's one of the new I can enjoy leaving on for hours (or days) at a time without finding it irritating enough to change stations.
