That's not all radios for sure. For example the Bulgarian Radio 1 seems to be almost exclusively music. Sometimes there are advertisement blocks that are long, but usually it's just music. Then there may be local stuff like college radios (e.g.: KGRG) that won't have as many advertisements, if any. In Slovakia there used to be Rádio Anténa Rock that was also mostly music as well, but they shut down as it wasn't profitable. They are now owned by Bauermedia and operate as "Rádio Rock" with only 3 low-power FM transmitters which barely cover 2 cities. At least they're in DAB+.
Anyway, there are some radios that do not have as many advertisements.
