"Say Aha" was released on November 24 in the UK. The song appeared in
television advertisements for
Samsung. In the United States, a remix of "Say Aha" (as well as a remix of "
L.E.S. Artistes") was featured in commercials for the
Ford Flex.
NME said that the song "loses out considerably in the amazingness stakes simply by virtue of not being 'L.E.S. Artistes'. But [...] this is jaunty, dancehall-flecked and it's perfectly fine," giving the song an eight out of ten. A review from
Music Week said the single "sounds sparkling" and "boasts a great chorus".
Pitchfork Media described "Say Aha" as "perfect new wave bubblegum-- 2 Tone keyboards, phaser effects, a stomp-ready chorus, and a surf guitar solo to finish." The review said that the song "evoke[s] that moment when rock's aggression met reggae's drive and depth".
The Times labelled the track "annoying/endearing" but "worthy of the hype." ==Music video==
