Next Batter Up: Walk-Up Music

Next Batter Up: Walk-Up Music is a Chrome extension that lets teams create custom walk-up and walk-out song intros for baseball and softball players. It supports Apple Music songs (with an active subscription) or your own audio files, and lets you record or generate AI-powered voice intros with five natural-sounding voices. Pair intros with music, use fade-outs, and create playlists for warmups, post-game celebrations, or themed events.

Organize multiple teams, save lineups, scrub or trim audio precisely, upload your own intros, and share lineups with other coaches or parents. Ideal for Little League, travel teams, school leagues, and adult leagues who want a pro-level sound without the hassle.
