Most lists are one writer's opinion or a copy of the big-league lineups. This one is counted from real youth teams on GameDay DJ, updated through the season, clean versions only.
GameDay DJ reads the lineup card from a photo, gives every player a stadium announcer intro, and plays the walk-up on a tap. Families pick their own kid's song from their phone and it shows up on the coach's screen. Once a team is locked in, a whole game plays with no signal.
Scan the lineup card, let each family pick the song, tap to play at the field. First team free, and it works with no signal.
Every row is the number of players on GameDay DJ teams who chose that song as their walk-up this season. Each team counted once, demo teams left out, versions of the same song merged, and only songs a public music catalog rates as clean. Nothing is padded and nothing is invented: if a list is short, that is how many teams have chosen so far.
