Just mention for example bands of your own country which you like, no problem if they don't sing in English, bands are bands no problem in which language they sing! only one thing: they shouldn't be famous in other countries..so don't mention within temptation when you are dutch, or rammstein when you are german
But if you like you can also mention bands from other countries that you know, but that most in your country don't know, but which are still very good! Don't need to be European bands ofcourse! Japanese, Mexican, Australian bands, it's all ok
In other words, just put some band names of unknown bands here (at least unknown in europe generally, they may be very famous in your own country but only not in the rest of europe
), so that all can hear how music in other countries is like, and so that maybe some discover their new favourite band!! Kind of band promotion topic, indeed 
Oh and btw, it don't need to be bands, although i speak of bands all the time, but singers/rappers/dj's whatever, are ok too, ofcourse 
Hope here post some more people, so that there are móre bands and so that it's nicer!!
