How does one go from affable, unassuming club DJ to one of the hottest, most in-demand producers in the game in just under a year and half? Beats us. We're pretty sure, however, that Frank E can tell you a thing or about that sort of thing. After crafting hits for Flo-Rida, T.I. and Plies, homeboy was reportedly summoned to the studio earlier this summer by Madonna to work on songs for her upcoming greatest hits package, which is slated for release next Spring. (Nice work if you can get it, eh?) See Madge's memo about the sessions and listen to Frank E's alleged demos -- one for a track titled "Revolver," as well as a studio version supposedly featuring Madge and Lil Wayne, and another demo of a track called "Put Ya Lights Down" -- after the jump.
