Who will take the crown this summer?
It's almost summer again - not that it's going to make a difference to those of us in Singapore - and that means the race to be the season's biggest track has begun.
In 2013, Robin Thicke and Daft Punk topped the charts with Blurred Lines and Get Lucky respectively.
Ed Sheeran's Sing and X Factor contestant Ella Henderson's Ghost came out on top in 2014.
We're only four months into 2015 but we have already been treated to dozens of great hits.
Ellie Goulding, Taylor Swift, Maroon 5, Rihanna and Carly Rae Jepsen are just some of the artists who've produced songs that we spent the first half of the year singing in the shower.
But who will be crowned the king/queen of summer 2015?
Let's take a look at some of the contenders, before you cast your vote below!
Taken off the Furious 7 soundtrack, this moving track is responsible for making grown men cry.
If you've seen the film, you'll probably remember that it was played during the tribute to the late Paul Walker.
Official Charts reported that the song had overtaken Ellie Goulding's Love Me Like You Do to become the fastest selling single of the year.
If you're still not sold, maybe you should check out Fast and Furious star Vin Diesel's rendition of it.
The 29 year-old Canadian's voice is stuck in our heads...again.
Following the massive success of her breakout song Call Me Maybe in 2011, Jepsen went on to release several other catchy singles such as This Kiss and Tonight I'm Getting Over You.
I Really Like You, yes there's only one "Really" in the title, is a song that will irritate you at first, then go one to become a guilty pleasure of yours.
Say what you like about it but there's no doubt this ditty, like Call Me Maybe, will remain in your memory for years to come.
Oh don't forget the awesome music video featuring Tom Hanks!
The music video for this song sparked plenty of debate when it was released.
Some thought the Grammy-winning band actually crashed weddings of unsuspecting couples in the video. Others argued that they were staged (for the record, it was partly staged).
The video has been viewed more than 342 million times since its release on January 14, and the song has topped charts worldwide.
Sugar will make you want to get up and dance and is probably one Maroon 5's most addictive songs to date.
The man who's brought us some of the naughtiest hits is back with Want To Want Me.
This time round, the song's beat is a lot more familiar. It could pass off as something by Bruno Mars if it weren't for Jason Derulo's signature vocals.
Unlike 2013's Talk Dirty and 2014's cheeky Wiggle, Want To Want Me sounds like something straight out of an 80s disco.
It's slowly making its way up the Billboard Hot 100 Chart.
The "oldest" song on the list and perhaps the most popular one.
DJ Mark Ronson, who worked with Amy Winehouse on Valerie, teamed up with Bruno Mars for the Motown-inspired sounds of Uptown Funk.
It has spent 22 weeks on the Hot 100 Billboard Chart and was only recently pushed down to number two by Wiz Khalifa's See You Again.
The track also won Ronson the award for British Single of The Year at the 35th Brit Awards held in February.
You know you have a hit on your hands when the First Lady of the United States dances to it.
Watch Michelle Obama show off her moves on The Ellen Show.
In 2012, Korean rapper PSY nearly broke the Internet when Gangnam Style went viral.
This year, another Asian has made waves on YouTube - Singapore's very own Chen Tianwen.
Unbelievable was recorded for an episode of the local sitcom Spouse For House.
No one expected it to be such a hit worldwide.
Time even called it an "instant mood lifter for the day".
It's highly unlikely that the Ilo Ilo star's song will find its way onto international charts but we'll be talking about this one for months to come.
"This feels like my second peak in the industry after working hard for so many years," Chen said of the video's success.
Unbelievable has been viewed more than 800,000 times on YouTube. It has also spawned several covers and remixes.
