Radio Havana Cuba has a music show on Sundays. Radio Japan has music shows called "Pop joins the world" and "J-Mellow" - check their schedule online. Radio Sweden has a music show called "Headset".

Sorry, I don't have the exact schedules for these programs. I have a page of links to some stations that broadcast in English, and some of these sites have program guides:
