During each home game beginning with Friday's opener through June 7, two songs will put up to a vote by text. Fans must be in the ballpark to vote and will be limited to one vote per game.
The winning song at each game will be played in the middle of the sixth inning and advance to the next round.
Fans can go to royals.com/playitforward for a complete list of songs and an updated bracket.
