In the first original track written by the a cappella group Pentatonix, the group is searching for some deep "can't sleep love" in contrast to the frivolous relationships full of "kissin' in the moonlight, movies on a late night." PTX wrote and produced the album's lead single with the help of songwriters Elof Loelv, Kevin Figueiredo, Teddy Peña and William Wells. It was also the first time the band worked with Kuk Harrell, a notable songwriter and producer who penned hits like "Umbrella
" and "Single Ladies (Put a Ring on It)
" as part of a songwriting team with Christopher "Tricky" Stewart and Terius "The Dream" Nash, and also produced songs for American Idol
PTX baritone Scott Hoying recalled in a track-by-track commentary: "'Can't Sleep Love' was a song that was originally sent to us by the label unfinished, and we were obsessed with it, and we were in Europe and we started arranging it and it just worked, because it sounded very full but it was still like very, very vocal. And so like this is the perfect song for us."
