"Lost in Music" is a song by American vocal group Sister Sledge, released in July 1979^[1] as the third single from their third studio album, We Are Family (1979), an album entirely written, produced, and arranged by Nile Rodgers and Bernard Edwards (of the group Chic). The "intoxicating" song was a no. 35 hit on the American R&B charts.^[2] In 1984 and 1993, "Lost in Music" was re-released in new remixes.

"Lost in Music" was one of the group's biggest hits, charting at No. 35 on the US Billboard R&B chart (then called the Hot Soul Singles chart).^[3] It also reached the UK top twenty in three separate decades. The original version reached No. 17 in 1979,^[1] a remixed version^[4] reached No. 4 in 1984,^[1] and another remix reached No. 14 in 1993.

Cash Box described the song as a "very Chic tune" with "sparse, elegant instrumentation and a "fascinating" hook.^[5] Richard Smith from Melody Maker wrote, "'Lost in Music' was a slice of pure pop heaven. A song about the simple thrill of going out dancing, every bit as thrilling as the feeling it was trying to describe."^[6] Alan Jones from Music Week gave the 1993 remix three out of five, adding that "once again the original Chic hallmarks are ditched to turn the track into an edgy, percussive rattling slab of Nineties dance music."^[7] Record World said that the "clear clean production, snappy percussion, & choir-like vocals are overwhelming."^[8]

A cover version of the song appeared on British post-punk band the Fall's 1993 album The Infotainment Scan;^[13][14] their "radically different" version has been read as a critique of the "unfair derision of the disco genre".^[15]
