Tap the world and listen,
“Tap the world” could mean:
1) Listen in as a spy would (like “phone tap”), which goes well with the following “and listen”
2) As he began to write his raps, his artistry was also inspired by having a lot of sex with different nationalities of women (to “tap” is to make love); even though he’s Muslim, Lupe has admitted to having a “genuine interest in women”
3) It could mean he is figuratively tapping the world on the shoulder to get our attention and asking us to listen to what he has to say.
4) It could mean that, as he began to jot, he ‘tapped’ the world (drew lyrics from the world around him because he is socially conscious) and then let it be heard (drop).
