Rap that'd sound good even if you didn't understand a word?

Wow, this is absolutely beautiful. Thank you.

(thanks to everyone else too; right now, YouTube is banned in China, so it’s a little slow going trying to track down y’all’s recommendations.)

Jovanotti – Italian rap (and, later, mellow funk) singer. I love it, and I don’t understand Italian.

Control Machete. Mexican rap in general should be better known than it is.

Jovanatti - Serenata Rap. This one’s worth listening to.
