Apparently Lupe Fiasco recorded his own version of 'Airplanes' featuring vocals from Paramore's Hayley Williams before passing on the now Grammy-nominated hit.

B.o.B picked up the track and featured Eminem on the hit single, off his debut studio album, 'B.o.B Presents: The Adventures of Bobby Ray.'

Lupe's success wasn't exactly hindered by his decision to give up the track -- his latest studio album 'Lasers' debuted at No. 1 on the Billboard 200, earning the hip-hop artist his second Top 10 album and his highest entry on the chart. Lupe is also featured on B.o.B's album on the track 'Past My Shades.'
