Thursday's episode of Greatest Hits, ABC's nostalgia trip concert show, featured songs from 1995 to 2000, aka the height of the boy band era. The princes of the late '90s, the Backstreet Boys, showed up to do one of their biggest hits, "I Want It That Way."

They were joined by '90s baby Meghan Trainor for a little back-and-forth shuffle-dancing. That sizzling sound you hear is women all over the country burning with jealously that Trainor got to do the "don't wanna hear you" key change with the cutest Boys of 1997. Check out the performance in the video above.
