It's official: this week's Uncharted  ballots have been counted, and the Deadlies  have won the election by a landslide. For the second week running, Los Angeles-based rock band coast along at No. 1, thanks to nearly 290,000 MySpace Music song plays in the past week alone. From charged, Muse-like guitar riffs to acoustic ukelele ballads, the quartet's stylistic versatility is no doubt what attracts their vast online audience. The Deadlies play Billboard Pro's SXSW showcase  this Saturday at Buffalo Billiards in Austin, Texas.
Portland rock trio Galaxy Farm  are moving up in the world, taking the No. 21 spot after ranking at no. 32 last week. With more than 20,000 additional MySpace Music song plays this week, the group maintains an active conversation with fans on Facebook about their forthcoming full-length release.
Few editions of Uncharted come without a handful of star-powered acts. This week''s installment includes Diggy Simmons , best known from his role on the reality series "Run's House" -- he is the son of rapper Rev Run of Run-DMC. The young hip-hop artist gained over 12,000 Twitter followers this week alone, and collaborations with established artists like Lupe Fiasco and Pharrell Williams have certainly helped him follow in his father's footsteps.
The freshest face on the chart this week is Selah Sue , the Belgian reggae/soul singer most famous for her duet with Cee-Lo Green  on the track "Please" from his 2010 album The Lady Killer. Born Sanne Putseys, the singer raked in over 28,000 Last.fm song plays and nearly 24,000 Wikipedia page views. Selah's soulful style and talent will no doubt soon place her among the ranks of famous wailers like Adele  and Amy Winehouse .
Finally, we say goodbye to another graduate: the self-proclaimed "white boy awesome" Mac Miller . The 18-year-old hip-hop artist, who ranked at No. 50 on Uncharted last month, carved out a spot on not one but two Billboard charts for his track "Knock Knock" last week, at No. 36 on Rap Digital Songs and No. 48 on R&B/Hip-Hop Digital Songs. The up-and-comer recently released a mixtape and is currently on tour with Wiz Khalifa .
