Youngblood

The title track of 5 Seconds of Summer's third album, "Youngblood" finds vocalist Luke Hemmings reflecting on the push and pulls of a relationship. Youngblood Say you want me, say you want me out of your life And I'm just a dead man walking tonight But you need it, yeah, you need it all of the time Both Hemmings and his girlfriend are stuck in a dysfunctional cycle of breaking up and getting back together. However, as the song progresses Hemmings gets increasingly bitter, as he calls out his lover for calling someone else "baby" rather than him. So who you been calling, baby? Nobody could take my place When you looking at those strangers, hope to God you see my face

A "youngblood" normally refers to someone new, usually inexperienced, who has been bought into a team or organization. However, the song seems to have a Fall Out Boy influence and the title, may be a nod to The Young Blood Chronicles a series of music videos produced by Fall Out Boy, featuring each song from their 2013 album Save Rock And Roll.

5 Seconds of Summer wrote this with pop wizards Ali Tamposi ((Kelly Clarkson's "What Doesn't Kill You (Stronger)," DJ Snake featuring Justin Bieber's "Let Me Love You") and Andrew Watt (Kygo featuring Selina Gomez's "It Ain't Me", Camila Cabello's "Havana"). The production was handled by Watt and frequent Post Malone collaborator Louis Bell.
