One thing that strikes a lot of non-European viewers of the Eurovision Song Contest is that many of the songs are sung in English.
Outside of the ESC, are most modern songs produced in Europe typically produced in the native language of the singers, or in English? I assumed the former, but the mockumentary Get Ready to be Boyzvoiced was in Norwegian, except for the singing, which is in English. If it's common for modern songs to be in English, then maybe there's nothing aberrant about the ESC at all.
If the ESC has an unusually high proportion of English-language songs, is it because the lyrics are more likely to be understood by a large number of voters, or is English seen as a "cool" language, or is it something else?
I checked List of languages in the Eurovision Song Contest, but it only listed when people used English, not why.
