Symphony Clean Bandit & Zara Larsson
We've had some pretty EPIC battles in the Vodafone Big Top 40 - but these huge tunes wiped the floor with the competition and spent WEEKS reigning supreme!
Bruno Mars absolutely dominated the Vodafone Big Top 40 in January 2011 scoring four of the five Sundays in the month. He was finally knocked from his perch by Jessie J's 'Price Tag' featuring B.o.B.
Back in 2011 RiRi and Calvin spent four weeks in pole position, however there was strangely a two week period in the middle of their reign where Professor Green's 'Read All About It' borrowed the No.1 spot.
Pharrell Williams, Daft Punk and Nile Rogers is pretty much all you need to make the funkiest song of the decade. The 2013 anthem spent an entire month at the top between April and May.
Jess Glynne and Clean Bandit are a winning combination with two No.1 singles together. However it was their single 'Rather Be' which gave the pairing an entire MONTH at the top of the pile.
Fifty Shades Of Grey was undoubtedly one of the biggest movies of 2015 and with a film as huge as that, comes a soundtrack just as sexy. Ellie Goulding's 'Love Me Like You Do' knocked 'Uptown Funk' off the top and began its own 4 week stay at the top.
As summer 2015 broke out in the UK, so did Jason Derulo's 'Want To Want Me', the singing and dancing sensation knocked OMI off and began a hot streak of four weeks at No.1.
It was the comeback we were ALL waiting for and it finally happened in October 2015. 'Hello' was the first track from Adele's third album, '25', and ended up breaking pretty much every record in history!
Talk about a breakthrough single! Nobody had really heard of Meghan Trainor when her debut single 'All About The Bass' stormed the top 40 and stayed at the top for a gigantic five weeks. She was finally knocked off her perch by Cheryl's 'I Don't Care'.
James Arthur's 'Say You Won't Let Go' came out of absolutely nowhere and knocked The Chainsmokers off the No.1 spot with ease in late 2016.
We saw the likes of ZAYN and Shawn Mendes both score No.1 singles at the start of 2016 however it was Danish ghetto pop band Lukas Graham who notched up more than both of those combined, wow!
Throughout February and March 2012 there was only one song that people were humming to themselves, and it was from Australian artist Gotye. 'Somebody That I Used To Know' was finally toppled from the top spot after 6 weeks by Chris Brown's 'Turn Up the Music'.
Pharrell had spent just one week off the top of the chart with 'Get Lucky' in 2013 before this catchy Robin Thicke collaboration took over and spent a mammoth SIX weeks at No.1.
Justin Bieber's 'Purpose' album has (so far) served up three No.1 singles, 'What Do You Mean?', 'Sorry' and 'Love Yourself'. However it was the latter which notched up an impressive seven weeks at the top spot.
The current record holder is...Mark Ronson and Bruno Mars' 'Uptown Funk'! The single's chart dominance spanned over both 2014 AND 2015 after it was rush released following Fleur East's unforgettable performance of it on The X Factor.
