Described as an electropop, synth-pop, and "house-fueled" album, PC Music Volume 2 features the group's trademark "marriage of pop hooks, rubbery synths, and beguiling female vocals," as well as "a mix of styles appropriated from both the dance underground and Top 40".

[1][2][3][4] Many of the songs feature an "allergy" to the polyrhythms typical in dance music, like on "Super Natural" "where beats, hand claps, and screamingly dense Eurodance keyboards are all pulsing at you as one".

[4] "Super Natural" features Canadian singer Carly Rae Jepsen, a choice that was noted for breaking the mould in comparison to the "often metallicized" and manipulated vocals usually present on PC Music songs.

[6] Rachel Aroesti of The Guardian gave the collection a perfect score, and said that following the hype of Volume 1 "this second compilation provides an opportunity to appreciate the music on its own terms – and it feels more beautiful and progressive than ever before.

[1] Rich Juzwiak of Spin praised it for being "more mature, less obnoxious, and much more deserving of the early hype PC Music received" and "actual songs" as opposed to its irony-laden predecessor.
