Not Music is the tenth studio album by English-French rock band Stereolab, released on 16 November 2010 by Drag City and Duophonic Records.

[6] Arnold Pan of PopMatters found that "the catchiest tracks on Not Music make a good soundtrack for strolling down memory lane, with Stereolab offering fresh takes on old triumphs, rather than just reliving them.

"[13] Rebecca Raber of Pitchfork was also positive, writing, "I suspect it won't be long before we realize that the leftovers of a band like Stereolab are still better than main dishes offered up by many of their peers.

"[12] AllMusic critic Heather Phares described Not Music as being "all over the place in the best possible way", noting that it would especially appeal to listeners interested in "Stereolab's gracefully intellectual side".

"[17] Under the Radar writer Hays Davis was more critical, describing Not Music as "one of those albums of extras that disappointingly lays bare why these tracks were excluded from those that initially found a release.
