Adele scored the No.1 spot just DAYS after the release of 'Hello' however this is where the hard work starts for the singing superstar.
She came, she saw, she conquered. Adele's 'Hello' was able to fight off tough competition from Justin Bieber's 'Sorry' last Sunday to knock Tinie Tempah's 'Turn The Music Louder' off the top after just one week. However it's now time for the title to be defended.
Too tough to choose? Here's a little bit about each track that'll help you decide who gets your vote...

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'
FUN FACT: The choreographer behind Justin Bieber's 'Sorry' music video is 23 year old New Zealander Parris Goebel who danced on Nicki Minaj's 'Pinkprint Tour'.

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.
