In the early Seventies, Atlantic R&B producer Jerry Wexler signed Willie Nelson; the duo shared a fondness for the Western swing of Bob Wills and planned to record a tribute to the music. It got put off until just before Wexler's death in 2008, when they finally put this disc in motion. It was worth the wait: Nelson's laid-back croon acts as a warm dishrag over the fiddle, pedal steel, cowboy harmonies and roadhouse jazz of Western-swing revivalists Asleep at the Wheel. Jerry would be proud.

“My President”

Young Jeezy teams up with Nas on this track, in which he compare his own success with the idea of an African-American winning the Democratic Party's nomination in the 2008 presidential election. "When I pulled up in my car, that s--- was unbelievable to people in my neighborhood because they were like, 'We grew up with him. How the hell did he accomplish this?'" he told Rolling Stone. "I feel like it was the same way with Obama. I grew up all this time, but I've never seen a black man this close to running this country."
