The wait is over! Lauren Jauregui's debut solo single, "Expectations," arrived on Wednesday (October 24), and it definitely exceeds expectations.

The smoky, guitar-driven slow jam showcases Jauregui's powerful pipes and marks a clear departure from Fifth Harmony's airy pop material. "Wish I had no expectations / I wish that I could get it through your head / With no confrontation / I really wish we could talk about it instead," Jauregui sings, her raspy vocals rising into a pleading moan on the chorus.

Given the 22-year-old's rebellious streak, it should come as no surprise that the video makes a similarly strong statement. A black-and-white affair, the visual finds two versions of Jauregui roaming an empty house; one wears a white dress while the other, more sinister one rocks black leather. The latter Lauren performs an eye-popping dance during the song's ripping guitar solo, and the two finally meet in the end — to very messy, very unexpected effect.

For "Expectations," Jauregui linked up with British producer Kid Harpoon, who's no stranger to working with pop stars gone solo — he co-wrote and produced most of Harry Styles's debut album. Speaking to MTV News about her new song, Jauregui said, "I went right in the studio the day after I went through something that made me upset. … I wrote it really quick, too. It was like 30 minutes."

She added, "Just the context of it and the mood of it, I feel like is a really great introduction to the world that I'm about to give people."
