Yes, I listen to a lot of Japanese, Korean and Spanish music mainly, but I'll listen to music in any language honestly though. In my opinion, a good melody transcends languages.

i'm a sucker for a bit of german hip-hop

Mylène Farmer

All the time.

I'm from Spain so I listen to spanish music, but not too much.
Also some french songs

Fredrika Stahl and Lorie occasionally..

I sometimes use intro/ending songs from Animes such as Black Butler and Soul Eater
I don't care about the artists that sing the songs tho

Amen.

Selena and Celia Cruz are the true divas.

I also love German music: Rammstein, Wir Sind Helden, Xavier Naidoo, etc.
French: Francois Hardy, Vanessa Paradis, Sandy Cossett, etc.

duh i don't need to understand lyrics to like a song
