24. Travis Porter "Make It Rain" (2010)

In the not-too-distant future, the "carrot-stick" approach will be retitled "the twerk-precipitation method." And ATL trio Travis Porter will be to blame. The stop-start chorus and production are booty-motivating on a sonic level, but naturally it's Ali, Quez and Strap who are the primary cheerleaders of successful twerking strategies. Think of it as a modern-day rain dance, but with paying bills and rent as the real end goal. Also, getting rained on. With cash.
