For the New York Mets, and pretty much every other major league baseball team, individual player walk-up songs are a fairly recent development. Teams have long had their own organists to provide a clever, upbeat soundtrack to the on-field action. In 1970, Nancy Faust for the Chicago White Sox was the first team organist to start playing different songs for each home player as they stepped up to the plate.
The tradition evolved throughout the 1990s when the Seattle Mariners were among the first baseball teams to experiment with recorded walk-up music for each player.
