Now that the Wanted's reign over PopCrush's Sound Off has ended, it's time for two new competitors to go head-to-head in our battle of the songs. This week, we are pitting Jay-Z protege/Roc Nation newcomer Rita Ora and her new single 'Party and Bulls---' versus 'Like a G6' hitmakers Far East Movement and their new Justin Bieber-featured track 'Live My Life.'

On 'Party and Bulls---,' Ora shows off her smoky, sultry and soulful pop vocals over a bubbly beat. Ora's 'Party and Bulls---,' whose chant-like hook pays homage to Notorious B.I.G.'s song of the same name, boasts hard-hitting 808's while fusing electronic, hip-hop and pop elements, making for a catchy song that induces finger snaps, foot stomps and a whole slew of other dance moves.

Likewise, Far East Movement and Justin Bieber produce a danceable song with 'Live My Life,' except their track is much more of an intense club anthem (opposed to the sugary sounds of Ora), with whirring synth, Eurodance qualities and an epic, building chorus from the Biebs (whose voice has definitely matured a whole lot since 'One Time'). While 'Party and Bulls---' is also a celebratory track about having fun and letting loose, 'Live My Life' is targeted at all of the club animals out there.

So, whose track do you like better? Listen to Rita Ora's 'Party and Bulls---' and Far East Movement's 'Live My Life' (featuring Justin Bieber) below and cast your vote! The poll will remain opened until March 5 at 8AM EST.
