Most music playing on Danish radio is American or British or from outside Europe. Whatever is popular there will also be played here. I just checked a list of most played songs on a commercial channel, and only 12 out of 50 were in Danish. An additional 6 were in English by Danish artists.
I'm more curious the other way around. When does a European song break through over there, and why is it only French songs that make the cut without being in English.
Most of the English speaking European songs that are popular here seem to be pretty similar to American pop or rock, eg Scorpions, ABBA, A-Ha (Take on Me), obviously anything UK, could all pass as American. The occasional song like 99 Red Balloons or Du Hast is a bit unexpected but usually they’re magnetically catchy
Almost all the non English speaking songs I can think of off the top of my head that made it big here are Latin, like Despacito, La Bamba, anything Shakira, Enrique Iglesias. Probably the style and vibe they give off.
Stuff like Bon Jovi’s It’s My Life barely making it on the charts in the US but being #1 in Spain, Switzerland, Italy, Netherlands, Belgium, Austria is what perplexes me.
