... whereas who can't do a spot of rapping?

Fabolous might want to think a little harder before discussing his career path:

"I thought I was going to be an artist. I went to art and design high school. I drew cartoon characters. Then I realised I wasn't very good, so I turned to music."

Given that drawing cartoons doesn't always call for the highest level of artistic skill, this doesn't really suggest Fabolous viewed rap as a difficult option.
