Ariana Grande - 'Focus'

FUN FACT : After Ariana posted a photo of the 'Focus' artwork including a photoshopped Draco Malfoy, actor Tom Felton (Draco) offered to be in one of her music videos, to which Ari replied '1000000% yes!'.

Why should it get your vote:  Ariana has already had two No.1 singles ('Problem' & 'Bang Bang') and you can help her bag her third in two years.

Justin Bieber - 'Sorry'

Why should it get your vote:  Justin's new journey into a more dance orientated genre is highlighting exactly what the Canadian singer can do.

Sam Smith - 'Writing's On The Wall'

FUN FACT:  Sam had to edit the song a little after conversations with the producer and director of 'Spectre' to better reflect the stronger attributes of James Bond's character. Sam revealed 'because lyrically i'm quite a vulnerable writer, I am quite an emotional writer and James Bond is quite a strong character."

Why should it get your vote: The song is played over one of the most visually stunning James Bond movie intros in a long LONG time.
