B.o.B's 'Airplanes (Part II),' Featuring Eminem And Hayley Williams, Hits The Net

'Since the album is leaking, I want this one to come from ME,' B.o.B tweets about posting song.

There's been much hype surrounding B.o.B's debut album, B.o.B Presents: The Adventures of Bobby Ray, which is slated to drop April 27. The album's lead single and surprise hit, "Nothin' on You," featuring Bruno Mars, currently sits at #1 on iTunes' songs chart. But once the album's track listing was released, anticipation began to grow even more, thanks in large part to the Eminem feature on "Airplanes (Part II)."

B.o.B decided to unleash the track Monday afternoon (April 19) via his website, and it lives up expectations. The song features Em spitting another song-stealing verse, rapping hypothetically about what could have been failed opportunities.

"Let's pretend Marshall Mathers never picked up a pen/ Let's pretend things would've been no different/ Pretend he procrastinated, had no motivation, pretend he just made excuses that were so paper thin."

Em continues, listing off scenes from his now-famous narrative of a tortured childhood and his tumultuous relationship with his mother.

"Now pretend they ain't just make him angry with this sh--/ And there was no one he could even aim [at] when he's pissed at/ And his alarm went off to wake him, but he didn't make it to the Rap Olympics/ Slept through his plane and he missed/ He's going to have a hard time explaining to Hailey and Laney this food stamps and this WIC sh--/ Because he never risked sh--/ He hoped and he wished it."

The retrospective track also features Paramore's Hayley Williams on the hook, who was as surprised as anyone by the Eminem collaboration.

"I only found out about Eminem getting on the track like a month ago," she told MTV News. "As if the song couldn't get any better. He just slays me, he's such a genius."

B.o.B told MTV News

last week that it was a gift to work with one of his heroes. He said Em's manager Paul Rosenberg grabbed Slim Shady's attention with B.o.B's first mixtape, Cloud 9, and he kept Em abreast of B.o.B's work. He tweeted Monday that he wanted to share the song first, since his album was leaking.

"Since the album is leaking ... I want this one to come from ME. Hear 'Airplanes Pt. 2' ft. EMINEM & Hayley Williams of Paramore."
