I understand enough Spanish that saying Selena and Shakira doesn't count for me, but I listen to quite a lot of J-pop and have only limited understanding of the language.
I listen to some music in French like Les Nubians and MC Solaar, but that's about it. I listen to a lot of Dancehall and the patois might as well be another language.
I listen to music in foreign languages all the time, but it doesnt mean I am not interested into the meaning. If I like a song very much, I usually search for translations of the lyrics to give me an idea what the song is about.
