R&B legend Lionel Richie now has the second-biggest selling album of 2012, as his "Tuskegee" set has moved 789,000 copies according to Nielsen SoundScan, pushing the departed WHitney Houston's "Greatest Hits" collection to No. 3 with 784,000.  Both albums are still well behind the year's biggest seller, Adele's "21," which has moved an impressive 3.3 million copies.  With the success of his latest effort, Richie has sold more copies of "Tuskegee" than with his previous three studio albums combined.  Check out the album's latest single, a remake of "Endless Love" featuring Shania Twain, below.
