Lupe FiascoJay-Z was an early champion. Kanye featured his him on 'Touch the Sky.' So, who is Chicago rapper Lupe Fiasco's favorite rapper?

The spicy answer might surprise you.

Lupe, who has spent the past year quietly working on material his forthcoming release 'Lasers,' took time to shout a little about one new song, 'Solar Midnite,' in a message posted yesterday on his Myspace page.

"'Solar Midnite' is my first commercial release that I actually produced as well as wrote," Lupe wrote about the track, which appears on the soundtrack to the 'Twilight' sequel, 'New Moon.' "The 'New Moon' team asked me if I could do a song specifically for the film."

'Solar Midnite' is exclusive to the the iTunes version of the soundtrack, released on Friday (October 16). Nonetheless, Lupe says he's still extremely excited about being a part of the highly anticipated film.

"They invited me to an early screening of the unfinished film, from which I pulled different elements that I thought would translate into a great song," he wrote. "I pulled in vocalist and bassist Graham Burris and acclaimed musician Matt Nelson to help fill out my vision musically and ... 'Solar Midnite' was born."

Though not included on the physical soundtrack release -- an indie rock-heavy set featuring Death Cab For Cutie, Bon Iver, Sea Wolf and Radiohead singer Thom Yorke, among others -- 'Solar Midnite' will be heard in the highly anticipated film, which depicts a bizarre love triangle between characters Bella Swan, Edward Cullen and Jacob Black. "The song basically deals with the chaotic love story that takes place between the characters," Lupe explained in his post.

As for the music, Lupe said that the song channels rock band Red Hot Chili Peppers, "It's more on the rock side of my musical catalog and comes straight from my die-hard fanhood of Red Hot Chili Peppers and Anthony Kiedis, one of my favorite rappers."

One has got to wonder what Jay and Kanye will think of that.
