Personally, I prefer things I don’t understand because I don’t have to mentally deal with whatever bullshit they are saying. I can sing it a thousand times without ever thinking too much about it because I know the sounds and not the meaning of the words.
I can belt out a ton of Japanese or Russian music, because I started listening to help my language learning (classes, not self-guided), but I don’t actually understand the songs. I “know the words”, but that’s it.
