Alive by Sia
Just weeks after the premiere of her collaboration with Kanye West at New York Fashion Week, the writer to the stars (and the star herself) has just released a new single, Alive. A teaser to her upcoming album, This is Acting, the song has been playing the pass the parcel game before landing on Sia's lap. Originally written for Adele, Sia decided on keeping the track for herself. She then sold it to Rihanna, but not without seller's remorse. Fortunately for her, the B*** Better have My Money singer turned it down. While you can imagine both Adele and Rihanna's vocal chops working their magic on it, Sia's cracked vocals in Alive's dramatic build and chorus offer a deeper meaning to the song — one that's beautifully broken.

 Alive by Sia is available on iTunes.

On My Mind by Ellie Goulding
Here comes Ellie Goulding's entry into the realm of full-on pop. Three years after her last studio album, Halcyon, the indie-electronic pop singer has collaborated with producer Max Martin again for On My Mind, the first single off her upcoming album, Delirium. As with most of Martin's hits (he's the producer behind Taylor Swift's Bad Blood, Katy Perry's I Kissed a Girl and Goulding's Love Me Like You Do), it's primed to be pop's newest earworm. Yes, complete with one-dimensional and repeated lyrics masked (or not) by a great voice.

   On My Mind is available on iTunes.

Writing's on the Wall by Sam Smith
It's only a month till the world premiere of Spectre, but Sam Smith has already got us begging for Bond. A 007 theme song is as powerful as the man itself — you've seen and heard how Adele's Oscar-winning Skyfall drove the film's opening credits to haunting heights. We reckon Sam Smith's Writing's on the Wall's out to do the same. Except this time, Smith threads on an emotionally high line (literally too, with Smith hitting some high notes), perhaps nudging to a Bond who's more of a sensitive, new age kind of guy.

Writing's on the Wall is available on iTunes.
