I believe the answer is:

'andre 3000's genre' is the definition.
(I know that Andre 3000 genre rap)
This is all the clue.
(Other definitions for rap that I've seen before include "Type of popular music" , "Strike; music genre" , "Hit - "songs" by Snoop Dogg and Jay-Z, say" , "Knock; type of rhythmical speech to music" , "Sharply criticise" .)
