GULF SHORES, Alabama – Music legend Stevie Wonder will be the third headline act at the 2013 Hangout Music Fest, organizers announced today, and other new additions to the lineup include Baauer and Macklemore, the creators behind two of 2013's top pop music phenomena, "Harlem Shake" and "Thrift Shop."

Other new additions include the Yeah Yeah Yeahs, Imagine Dragons, Afrojack, Big Gigantic, Holy Ghost! Ra Ra Riot and the Wild Feathers.

The festival takes place May 17-19 on the beach in Gulf Shores. Most of the lineup was announced in mid-February, when Tom Petty & the Heartbreakers and the Kings of Leon were announced as the acts that would close out two of its three days.

Wonder needs no introduction, thanks to a titanic career stretching back to the early ‘60s. He has won more than 20 Grammy awards for his work as a vocalist, producer and arranger.

Baauer's "Harlem Shake" has been one of 2013's biggest hits, thanks in part to the viral popularity of an international dance craze inspired by the track. Similarly, Macklemore was a relatively little-known artist until he teamed up with producer Ryan Lewis and released the album "The Heist" late in 2012. The offbeat single "Thrift Shop," which celebrates the glories of secondhand fashions, was No. 1 on Billboard's pop chart for four weeks this year. According to the Hangout announcement, Lewis will join Macklemore at the festival.
