Toni Stone

Toni Stone is the high-energy, genre-blending pseudonym of composer/producer Katie Day, founder of the acclaimed music house Shortcake Music. With a background in scoring original music for Netflix, MLB, Dove, HP, and Logitech (among others), Katie is no stranger to crafting emotionally resonant, sonically precise compositions. Under the Toni Stone moniker, she channels that expertise into creating dynamic music made to move - both the body and the spirit.
Named in tribute to Toni Stone, the first woman to play professional baseball in a men’s major league, the project embodies grit, confidence & rhythm. Toni’s tracks range from adrenaline-pumping dance-pop anthems to vibey lo-fi beats for cooldowns and recovery. It’s music built for the full arc of a workout - or a life lived with intention.
Katie’s deep love of sports and performance sparked a curiosity about what makes functional music work. Through that lens, Toni Stone was born: an outlet to fuse melodic hooks with tempo-driven power, informed by both science and intuition. Her tracks hit hard, lift spirits, and help you push further.
Toni Stone's music has found fans not just among fitness heads and runners, but also among Cubs fans, thanks to Katie’s cult-favorite anthem predicting their legendary 2016 World Series win. With Toni Stone, she continues to blur the lines between commercial polish and creative freedom, offering soundtracks that are as empowering as they are infectious.
