Audio: Lupe Fiasco "Love Letter To The Beat" feat. Alicia Keys
So apparently this song "Love Letter To The Beat" was originally an Alicia Keys song produced by Chad Hugo, and meant for her '07 album, As I Am (didn't make the final cut, clearly). The song was then passed on to Lupe Fiasco for his upcoming album, Lasers. The release date for Lasers will be announced at some point this week.
