5. The Roots - "Rising Up"
From the go-go drums to Chrisette Michelle's soulful chorus and Wale's flawless verse, this is what a glorious mid-tempo throb sounds like.
4. Q-Tip - "Move"/"Renaissance Rap"
This twofer reminds us of the many reasons why Q-Tip is such a special artist. It's lively enough for the club and energetic enough for the gym. With a flip of the beat, a bubbly rap song descends into a somber subway jam, as Tip recalls his days as a young MC.
3. N.E.R.D. - "Everyone Nose"
This hilarious paean to booger sugar had all the girls -- and some guys -- fiending for more N.E.R.D goodness.
2. T.I. - "Swagga Like Us"
T.I.'s star-stuffed single instantly became an inescapable radio hit, club banger, and summer staple in 2008. To crown it all, a heavily pregnant M.I.A. joined the boys onstage for a Grammy performance...on her due date. Top that swagga.
1. Lil Wayne - "A Milli"
Weezy goes on a free-verse rampage, rambling about everything under the sun. You have no idea what he's saying, but you simply can't turn it off because his flow is so damn infectious.
