By contrast, Jon Caramanica from The New York Times argued that it "isn't a hip-hop song, but it is hip-hop-influenced." Ryce felt the song's music "represents the hip-hop contingent of" bass music, which is typified by rolling snares and jerky basslines, finding it "particularly symptomatic of a growing strain of music obsessed with 'trap '". According to Andrew Ryce from Resident Advisor, "Harlem Shake" is a hip hop and bass song, while both David Wagner of The Atlantic and Khal from Complex described it as trap, a musical subgenre with stylistic origins in EDM and Southern hip hop, featuring Roland TR-808 beats and drops. It has a high tempo characteristic of hip hop and a dance music drop. "Harlem Shake" features harsh snares, a mechanical bassline, samples of growling lions, and Dutch house synth riffs.

American rapper Azealia Banks released a remix to "Harlem Shake" on her SoundCloud page, which was subsequently removed at Baauer's request and led to a dispute between the two. However, according to Baauer, he has not received any of the money the song made because of the legal issues from not having properly cleared the samples. After the song became a hit, Mad Decent label head Diplo reached an agreement with the artists of the song's samples, which had not been contractually cleared before its release. "Harlem Shake" was well received by music critics, who viewed it as an appealing dance track, although some felt that it was more of a novelty song. During the song's chart run, Billboard enacted a policy that included video streams as a component of their charts. It also reached number three in the United Kingdom and number one in both Australia and New Zealand. The media response to the meme helped increase the single's sales, as it charted at number one for five consecutive weeks on the US Billboard Hot 100.

The single did not begin to sell significantly until February 2013, when a YouTube video set to its music developed into an Internet meme of the same name. Baauer added a variety of peculiar sounds to the song so that it would stand out. It also samples Plastic Little's 2001 song "Miller Time", specifically the vocal "then do the Harlem shake", which is an allusion to the dance of the same name. The uptempo song-variously described as trap, hip hop or bass music-incorporates a mechanical bassline, Dutch house synth riffs, a dance music drop, and samples of growling-lion sounds. It was released as his debut single on May 22, 2012, by Mad Decent imprint label Jeffree's. " Harlem Shake" is a song recorded by American DJ and producer Baauer.
