Think back to 2000, when you couldn't escape Ludacris's hit "What's Your Fantasy." It's been awhile since the song has been on the radio circuit, but Ludacris just brought it back into the pop culture stratosphere. The rapper graced The Tonight Show Starring Jimmy Fallon with an acoustic version of the song, featuring some backup from The Roots. He was there promoting Furious 7 [1], but this might just remind you how much you love him as a musician. Check it out below.
