×∞Multiplies (増殖Zōshoku, lit. "multiplication") was a mini-album and the third studio album by Yellow Magic Orchestra released in 1980. It contained a mixture of songs and instrumentals by YMO (including a humorous reworking of Archie Bell & the Drells' "Tighten Up"), interspersed with comedy sketches performed by Snakeman Show in both Japanese and English, with YMO participating in some of them.  The United States pressing compiled tracks from both this record and from Solid State Survivor (their previous album, 1979), which had not yet been released in the U.S., while dropping the comedy sketches.

Upon release, the US version was well received by the Stereo Review, which described the recording as "terrific" and the performance as "Techno-pop fun." The magazine stated that the "time is right" for the band's "highly technological blend of dance rhythms, heavy metal, and pop melodies" while noting that "Rydeen" in particular "sprints by at a fast clip, ticking off a sprightly tune against a continuous bass-and-drum texture," though the "more rock-style efforts" were not as well received, with the magazine stating that "YMO's electronic tricks" and "the rock sensibility just don't seem to mix." AllMusic later reviewed the Japanese version, describing the record as a "bizarre album" and scoring it 2.5 out of 5 stars.
