According to brand new popular myth, the song that was Number 1 on your 14th birthday is the one that defines your entire life.
Why? We’re not entirely sure. The theory started doing the rounds on Twitter last week thanks to user Swank0cean and it has since gone viral, with over 5,000 replies sparking elated or disappointed reactions.

Just for fun, we punched in the 14th birthdays of some music stars to see which song supposedly defines them best.
Lewis Capaldi: Tinie Tempah - Written In The Stars
It seems Lewis' success of late really was inevitable...
Tom Walker: Pussycat Dolls - Stickwitu
We reckon Tom'll be about for a while - plus, he recently became engaged. Confirmed.
Dua Lipa: Black Eyed Peas – I Gotta Feeling
We've gotta feeling that there's a lot more great music to come from Dua.
Stormzy, George Ezra: Rihanna ft. Jay Z - Umbrella
Of course a total banger, and Number 1 for over ten weeks - representing two of the UK's biggest artists.
Britney Spears: Robson & Jerome – I Believe/Up On The Roof
We have a feeling Brit won't be familiar with this one.
Calvin Harris: All Saints – Never Ever
We hope for Calvin's sake this emotional singalong doesn't define his life.
Anne-Marie: Tony Christie ft. Peter Kay (Is This The Way To) Amarillo
When the day is dawnin'
On a Texas Sunday mornin'
How I long to be there
With Marie who's waitin' for me there
Kylie: Madness – House Of Fun
We reckon Kylie will be pleased with this one.
Brandon Flowers: Robson & Jerome – Unchained Melody/White Cliffs Of Dover
Two timeless classics right there.
Ed Sheeran: U2 – Sometimes You Can’t Make It On Your Own
Except if you're Ed Sheeran.
Taylor Swift: Will Young – Leave Right Now
Please don't go anywhere, Tay!
