Ineed some on finding music. i have a nephew who is into rap, but when i find a rap song, it seems to either be too old for his taste or to him it isn't good enough. can someone suggest some good music for me to see if he likes it or not?

What is the name of the artist and the painting?

Why did arabesques become popular decorative designs used on sacred buildings and on the pages of the koran?
