In the film Trolls World Tour, Poppy (Anna Kendrick) and Branch (Justin Timberlake) find out that they're part of just one tribe of many—and that a whole universe of music exists outside of theirs. When Queen Barb (Rachel Bloom) and King Thrash (Ozzy Osbourne) threaten to take over all other forms of music with rock 'n' roll, it sends the Trolls on a thrilling adventure. The soundtrack is packed with familiar tunes: Bloom's lighthearted takes on certified rippers such as Ozzy's "Crazy Train", Scorpions' "Rock You Like a Hurricane", and Heart's "Barracuda", Sam Rockwell singing Patsy Cline's "I Fall to Pieces", and Anthony Ramos doing the Auto-Tuned robot on Daft Punk's "One More Time" are all shame-free crowdpleasers. But, not unlike Timberlake's "CAN'T STOP THE FEELING!", the originals here are the most rewarding. JT's team-up with SZA, "The Other Side", is a funky pop-R&B jam that's part Thriller-era MJ, part "Get Lucky". "Don't Slack", with Anderson .Paak, has a vintage R&B vibe with an irresistible bounce. And "Just Sing" is an uplifting ensemble tune (with plenty of the aforementioned stars, plus James Corden, Kelly Clarkson, George Clinton, Mary J. Blige, Kenan Thompson, Red Velvet, and Icona Pop) to roll the end credits on every feel-good movie from here on out.
