Pitbull, Ke$ha 'Timber' lead Billboard Hot 100 for second week, Katy Perry and Juicy J's 'Dark Horse' edges up chart

Pitbull and Ke$ha have once again knocked over all competition with "Timber." For the second week in a row, the country/pop/rap hybrid track tops the Billboard Hot 100, as Katy Perry's dark horse of a song "Dark Horse" continues to climb the charts.

According to Billboard, there are no new songs in the top of the chart this week, but there are quite a few shake-ups in the top 10.

However, the top three songs in the country remain the same. Pitbull and Ke$ha continue to bring down all the competition with "Timber," as the song tops the Hot Rap Songs chart and experiences radio success with an arrangement or formats and audiences.

OneRepublic are right behind "Timber" for a second week with "Counting Stars." The infectious rock song is leading Top 40 radio and made massive gains on streaming. And once again, similar to last week Eminem and Rihanna's former month long chart topper "The Monster" holds steady at No. 3.

The true story of the week's Hot 100 is the continued climb of Katy Perry's third Prism single "Dark Horse" (feat. Juicy J). Originally just a teaser track, "Dark Horse" found a massive following amongst pop music fans and was officially announced as the follow-up to the mediocre chart performer "Unconditionally." This week, "Dark Horse" led On-Demand songs and digital downloads, with 243,000 copies sold, leading to a rise to No. 4.

Seems like only a small amount of time until Perry notches yet another No. 1 single...

A Great Big World and Christina Aguilera's "Say Something," meanwhile, holds steady at No. 5.

Passenger's relaxed love song "Let Her Go" finds a new high point at No. 6, Lorde's "Royals" continues to fall down the chart and lands at No. 7, Avicii's "Wake Me Up!" stands strong at No. 8 and Imagine Dragon's "Demons" rises one spot to No. 9.

Finally, One Direction's folksy pop ballad "Story Of My Life" reenters the top 10 just barely to round everything out.

That means once again, Miley Cyrus' "Wrecking Bal" has stumbled back to the netherworld.
