This week was a big one for brand-new song releases, with Wiz Khalifa, Lana Del Rey, Rihanna, Taylor Swift and Kesha all releasing fresh, previously unheard tracks. All of the tracks are official singles from these five powerhouse artists, and we want to know which song was your favorite of the week.

Dad-to-be Wiz Khalifa might be prepping for parenthood, but it hasn't slowed him down at all professionally. The tattooed rapper dropped his first single, 'Remember You,' off of his forthcoming LP 'O.N.I.F.C.' The slower song featured superior R&B crooning from the Weeknd as Wiz delivers rhymes about his rich and famous lifestyle... and of course, his love for toking up.

Then there's Lana Del Rey, whose new single 'Ride' is the first off of her 'Born to Die' re-release. She's kept the classic formula that seems to work for her on 'Ride,' which has a melancholy tone and sadder lyrics. Of course, her voice keeps that smoky, sultry vibe to it, with her despair becoming prevalent in her vocal delivery.

Rihanna is up next with her new Sia-penned single 'Diamonds.' Is it just us, or does Rihanna crank out more new music than any other pop diva? Anyway, 'Diamonds' differ greatly from all of her 'Talk That Talk' releases, and has more of a 'Russian Roulette' vibe, without the weapon imagery that we would expect from RiRi. However, it does have a great hook on which Rihanna embraces her island accent, adding a more natural feel to the tune.

Taylor Swift has also been a busy gal, promoting the pants off of her upcoming LP 'Red.' Swift has just released another 'Red' single called 'Begin Again' in order to get her fans pumped for the entire album. Ms. Swift holds true to her country roots on this song, and unlike her first lead single, the kiss-off anthem 'We Are Never Ever Getting Back Together,' this lovestruck tune is all about the excitement and giddiness you experience at the start of a new relationship.

Finally, there's Kesha, who just released her first single since 'Blow' dropped in early 2011. The track is entitled 'Die Young,' and we seriously think she's got the next smash hit with this fun, catchy sing-along. We could see Kesha going to the top of the charts with the synthed-out, carpe diem song, which also features the singer's signature vocal-fry raps and an irresistible, lighthearted dance beat.
