It’s been four years since Usher released Looking 4 Myself, his last full-length album. Now, “after some ups, some downs,†he’s ready to release a follow-up, which will again cleverly substitute numbers for words in its title. Last night, on Jimmy Kimmel Live, Usher announced that Hard II Love will come out September 16. Listen to two of the album’s tracks, “Missin U†and “Champions,†the latter of which appears in Hands of Stone, a new film in which Usher plays the famed boxer “Sugar†Ray Leonard, below.
