5 Seconds of Summer teamed up with BBC Radio 1 DJ Scott Mills to create a new song called "Hearts Upon Our Sleeves" that they all are calling the "unofficial' World Cup song.

The boys (Calum, Michael, Luke, and Ashton) have a special place in their heart for soccer, or as they call it in their home country of Australia, football. Calum almost didn't even pursue the music career with the boys so he could play in a semi-pro professional football league. So it was only expected when Scott Mills asked for their help on this project that they would completely agree.
MTV said that "the catchy track is all about overcoming adversity and landing on your feet, while also perfectly encompassing those moments right before a big game. This “generic football” anthem as 5 Seconds of Summer call it, is anything but."
BBC Radio 1 is even giving the song away as a free download because that's how much they are loving the song!
With the World Cup right around the corner it's time to get in the spirit! Check out the music video which features everyone's favorite boys, One Direction helping out and playing a little bit of the game as well.
