VOTE: Will ZAYN Be YOUR Valentine's Day No.1 Single?

Its the weekend of LOVE! And to celebrate that, we've got an intense battle for the top spot on Sunday.

Well, well...what an insane countdown we had last weekend. After just ONE week at the top spot, ZAYN was knocked off his perch by none other than chart newcomers 'Lukas Graham'.

Find out the longest reigning No.1 singles of all time in Big Top 40 history!

As ZAYN found out last weekend with 'PILLOWTALK', it is a lot harder to stay at the top of the chart than it looks. Lukas Graham's '7 Years' rose up 29 PLACES to grab the No.1 title. Can they stay at the top longer than Mr. Malik?

Remember, you have to download your favourite to move them up the chart!

Here are your contenders to help you decide who deserves to top the chart:

Current No.1: Lukas Graham - '7 Years'

Download Lukas Graham's '7 Years'

Why it should be No.1: They knocked ZAYN off the top spot after ONE week, do they need to prove why they deserve to be at No.1 after that?

Zayn - 'PILLOWTALK'

Download Zayn's 'PILLOWTALK'

Why it should be No.1: ZAYN's solo debut single 'PILLOWTALK' only had a single week at No.1. Now we'll try and stay unbiased but ONE WEEK?! Surely it deserved longer than that!

Little Mix & Jason Derulo - 'Secret Love Song'

Download Little Mix's 'Secret Love Song'

Why it should be No.1: We couldn't think of a better fit than Jason Derulo and Little Mix. Just when you've been amazed by the ladies' vocals, you get Jason's incredible notes too!

Zara Larsson - 'Lush Life'

Download Zara Larsson's 'Lush Life'

Why it should be No.1: Last weekend Zara's 'Lush Life' was the ONLY new entry of the countdown. Surely the Swedish sensation can go one better and top the chart by lockdown on Sunday.

Keep it Capital from 4pm this Sunday to see who is this week's Vodafone Big Top 40 champion!
