Happy Saturday, PopCrushers! Not only is it time for your weekly installment of the PopCrush Mini-Mix, we're also kicking off the semi-final round of the Hottest Star of 2014 competition! And that means that PopCrush Mini-Mix 15 is chock-full of remixed tracks from some of our Hottest Star contenders, like Justin Bieber, Demi Lovato and many more.

The mix kicks off with One Direction's 'You and I,' and what better way to start your weekend than with the sweet sounds of 1D! (Right, ladies?) This version of the romantic ballad is interspersed with some club-like beats to give it a more up-tempo feel. Iggy Azalea's 'Fancy' is up next, and the sped-up version of the track completely energizes the playlist and makes you ready for a night out on the town. Of course, Justin Bieber's R&B groove 'As Long as You Love Me' always get the job done, and with those slick drumbeats in the background, we can't help but want to dance.

The mix then transitions into Demi Lovato's 'Neon Lights,' complete with handclaps and reworked beats. Macklemore's 'Can't Hold Us' is up next, and that's when the playlist really becomes a party -- when the rapper tells you to put your hands up, you better listen!

The last two songs on the Mini-Mix are the perfect numbers to help transition your night into serious party mode, with Katy Perry's endlessly catchy 'Birthday' and Jason Derulo's 'Talk Dirty,' which you know will kick the night off right. Let's get it started!
