I would like to know :)
On my city, I guess is reggaeton and stuff like that... but I hate it haha
Here it's mainly pop, or on other stations pop and even on occasion, if we're lucky, pop..... Although lately the songs have been leaning towards the club/remix/can you call this techno? style. We do have some stations that play 80s music, or rap, or indi music as well. (All english though, I've never heard a different language on the radio).
Here in Brazil ''sertanejo'' is maintream music so if you turn on the readio you're most likely to hear sertanejo universitário which is brazilian music, it sucks. But you an also find some american/british pop and Rock and roll.
In My Country (Morocco) It's Américan Rap & Pop.
