EW’s SiriusXM show EW Morning Live (channel 105) is out to do the impossible. Hosts Dalton Ross and Jessica Shaw want to determine the best TV show theme song ever broadcast. Being that this is bracket season, they’re sorting it out in the most appropriate manner posssible: With a single-elimination tournament that’s decided by your votes. It may not be the Big Dance, but it’s going to be big, and you might feel compelled to dance.

Since Tuesday, March 17, Dalton and Jessica have been playing a pair of theme songs each morning and debating their respective merits. Voting then opens below for you to choose which one advances. This will continue for the 63 days required to work through the bracket and reach a definitive answer, so be sure to tune in and bookmark this page—or simply never close your browser tab. That’s a pro tip right there.

Yesterday, Cheers defeated Hawaii Five-O. Voting for the final battle (The Greatest American Hero vs. Cheers) will open Wednesday at 8:45 a.m. ET.
