Since breaking out with his viral hit "Baby Girl" in the early 2020s, Disco Lines has become one of the most talked-about breakout names in modern American dance music — a house producer and DJ whose colorful, hook-driven sound has helped bring a new wave of listeners to the genre. Born Nick Sadler and based in New York City, Disco Lines built his sound around bright synths, driving basslines, playful vocal hooks, and the kind of undeniable pop sensibility that translates instantly from headphones to peak-time dance floors.

His breakthrough came with "Baby Girl," a track that exploded across TikTok and streaming platforms, racking up hundreds of millions of streams and turning him into one of the defining viral house artists of the moment. The single set the template for what followed: catchy, high-energy dance tracks built around unforgettable hooks and dance-floor-first production, delivered with a sense of fun that stands out in a genre often dominated by more serious tones.
