Eric Carlson, who is 29 and a lifelong White Sox fan, believes so. He met Faust as a teenager when he approached her booth behind home plate during a game to suggest she play “Around the World” by the group ATC.

When he returned to his seat and heard the strains of the song fill U.S. Cellular Field, Carlson said: “I felt special. I was thinking, of all the people in the stadium, she was playing that song for me.” Speaking by telephone, he added: “Most of the players, they don’t even want to give you the time of day anymore. But Nancy’s very down to earth and approachable.”

Carlson, though part of the generation that is the target of baseball teams’ entertainment upgrades, remains an unabashed fan of Faust. “Some of the songs she plays, I feel they actually sound better than the originals,” he said, adding: “I’m a Sox fan, so I’ll still go to games after this year. But it won’t be the same.”

Society has changed, Faust said, and the differences are reflected in ballpark entertainment. Whereas she used to play a song in its entirety, she is now limited to 20- or 30-second snippets. “What I’m doing is sound bites,” she said, adding, “I don’t want that to be my legacy.”

Since 2005, she has worked only day games. The team is interviewing organists for her position.

The people who say organ music gives a ballpark the feel of a cathedral are being supplanted by the likes of Guillen, the White Sox manager who grew up in Venezuela, where he said organ music was not part of the game-day experience.

Guillen compared Faust’s music to the vuvuzela, the South African horn. “At the beginning of the season, it’s fun,” he said. “Now in June or July, it gets old.”
