THE PERMANENT WEDDING AND BAR MITZVAH PLAYLIST

You know one when you hear it: A song that’s not just headed for #1, not just a sales, airplay and streaming monster, but one that’s going to be around forever.

By forever, we mean it will be used henceforth to get people pumped at social gatherings—they’ll be go-to selections for DJs at weddings, bar mitzvahs, proms and kindred confabs, galvanizing folks of all ages, genders, ethnicities and orientations to flood the dance floor, despite the logistical challenges of boogieing in a floor-length gown or rented tux.

That’s what we thought the moment we heard Justin Timberlake’s new Trolls track, “Can’t Fight the Feeling” (RCA). It’s a big, joyous groove that brings the heady delights of disco and Michael Jackson into the present. It's currently #1 at iTunes, and it'll be spinning at benchmark celebrations henceforth.

Other recent examples include Pharrell’s “Happy” (Columbia), Mark Ronson’s “Uptown Funk” (RCA), The Weeknd’s “Can’t Feel My Face” (Republic), Daft Punk’s “Get Lucky” (Columbia), Taylor Swift's "Shake It Off" (Big Machine) and Meghan Trainor’s “All About That Bass” (Epic). DJs will weave these into playlists alongside Kool and the Gang’s “Celebration,” The Bee Gees’ “Stayin’ Alive,” Young MC’s “Bust a Move” and The Jackson 5’s “I Want You Back” from now until doomsday.

We feel pretty sure JT’s latest will join that society of playlist perennials.
