Haha, matey, just to clarify:
Nujabes wasn't a rapper, actually :]

He was a producer who made the beats (=backing music),
afterwards, he used to invite rappers from all over the world to join him in the studio and sing;
I don't know whether he composed the lyrics to some of the songs himself, but I think most
of the original artists did.

Nonetheless, it was all thanks to Nujabes and we all honour him deeply.
May He Rest In Peace


(Btw, if you like these two songs, you should REALLY listen to the others he has! I've got most of his works, and they are simply A-MAZ-ZING)
