Nas drops a double entrende.

1. Going with the previous line he’s the best at fucking.

2. He’s the best ever at rap. Many agree, all because of this one album.

Although there is a missing word in this line, Nas is comparing himself to Batman and the bat signal.

Whenever Batman (in this case Nas sees it, he comes to the scene).

This could also be a double entrende.

1. He pops right up like the bat symbol would pop into the skyline.

2. He arrives, to the scene to be a part of whatever is going down.

Shelia E. was a grammy nominated singer and pianist, she also collabed with Prince who was mentioned in the previous line.

Like Nas, Shelia is still active with her music today.

Nina Simone was an African American singer who preformed or wrote songs in a variety genres of music, (such as classical, jazz, the blues, and much more.) Given the time period he’s probably getting this album.

The girl was trying to tell Nas they were inseparable and they would be together for as long as they were alive.

Remind you of anyone?

The neighborhood where Nas grew up and was born in.

Talking about a 45 colt handgun an extremely old weapon (dates back to 1872), and has an interesting history.

Nas has mentioned Hennessy so many times next to Alize it may be one of his favorite drinks.

Hell, they even let him go on a tour of their spirit producing facility.
