The Guest Appearance: T.I.
The Song: "In The A"
Why We Enjoyed It: While you could make the argument that Ludacris (who is also featured on this track) deserves a spot on the list, we've gotta give it up for Tip. He sets this hard-hitting A-Town anthem off properly by riding the beat to perfection. If this doesn't get you excited for T.I.'s new album, Trouble Man: Heavy is the Head, to drop later this month, nothing will.
