If you haven't seen Greatest Hits, you're missing some great performances!
The ABC show features famous artists from the '80s, '90s, and '00s paired with contemporary musicians for some new takes on old songs!
While the possibilities are endless, on Thursday night's sophomore episode we already had our biggest duet dreams come true as Meghan Trainor, the Backstreet Boys, Tori Kelly, Jewel, and Hanson all performed!
