Pop Quiz time! We're about a month away from the 2021 iHeartRadio Music Festival which of course goes down in Las Vegas. Tickets are on sale for that right now as well as the Daytime Village going down Saturday during the day. You can pick up your tickets for all the iHeart Music Festival events right here. In honor of the festival this weeks Pop Quiz is all about the performers at this years festival. Producer Frasier will play a lullaby version of a hit song by a 2021 iHeartRadio Music Festival performer and we see who can guess it the fastest between Mario and Courtney. Listen back to the hilarity below!
