"Euphoria" received critical acclaim. In a review of
Looking 4 Myself, Matt Cibula of
PopMatters commented that Usher "absolutely rips '
Climax' and 'What Happened to U', nails party anthems like '
Scream' and 'Euphoria' to the wall, and puts across harder things even while multitracking himself 35 times over with the greatest of ease." Nathan S. of DJ Booth wrote that "'Euphoria' hews even closer to the 4 AM in Ibiza template, as does the essentially identical Scream."
People's Chuck Arnold wrote that Usher "is an Ibiza-ready club kid on electro thumpers like current single 'Scream' and the Swedish House Mafia-produced 'Euphoria' that build on the success of '
OMG', '
DJ Got Us Fallin' in Love' and '
Without You' (with
David Guetta)." Regarding the song Jody Rosen of
Slate wrote that "Euphoria" "is an absurdly bombastic dance track, concocted by Usher and a few hundred thousand Scandinavians." Alex Macpherson of
guardian.co.uk was more critical to the song and labeled it as "eurotrash trance", while Danny Walker of
RWD Magazine called the song pacy. According to Carrie Battan of
Pitchfork Media Usher "sounds most uncomfortable and the least sharp on overblown club tracks 'Euphoria' and 'Numb', and the presence of rote numbers is almost comically predictable." Katherine St Asaph of Popdust stated that the track would sound great in the clubs, however it isn't standout by any means, further stating "Usher and Swedish House Mafia talk about euphoria, but what they deliver is perfectly passable excitement." ==Credits and personnel==
