Sonic Boom commentary of the track, before the Congratulations sessions at the Blanker Unsinn Studio on 2010: "Love? Or Confusion? Reality? Contusion? Subterranea or Sub-fusion. The Quest begins."

The single was added to BBC Radio 1's C-Playlist in May 2010 and later upgraded to the B-Playlist.

On June 29 the single was released as a digital download on iTunes, with the name of "It's Working Digital 45" and contains the Air and Violens remix.

On June 30 the remix by Air was given as a free download on RCRD LBL.

"One of the few songs on Congratulations to have been road-tested live, 'It's Working' dives straight into a Murmur-era R.E.M. riff, its jittery rhythm giving way to a reverbed-to-fuck Andrew Van Wyngarden vocal. Little dynamic flourishes build 'It's Working' up to a psychedelic (think I'll be using that word a lot) climax, before it pauses briefly for a Motown interlude and then, umm, a bongo solo. There's a truckload of ideas chucked into 'It's Working', but somehow it works. Attention-grabbing from the off—MGMT put the ace in spaced-out."

"'It's Working' was the first track demoed for the album and it immediately marks its patch a bold distance from Oracular Spectacular. In place of the grumbling synthesizers and neon electronica you might have been expecting, the track builds its house on harpsichords, flutes and Zombies-esque guitars. What's more, the hook—and there most definitely is one—takes a good 12 bars to reveal itself.

This is not 'psych rock inspired' like Oracular—this is full-blown, glorious bar-for-bar psych rock pastiche.

Perhaps predictably for a psych track, 'It's Working' is also about drugs. What's more curious, however, is that it's not about LSD. It's about all the ecstasy the boys regret gobbling up in the early throes of their success."

MGMT says in an interview for Pitchfork about the song: "We just shot the coolest video in Paris with director So Me [Justice's "D.A.N.C.E."] for 'It's Working'. In it, Ben and I find this box and these instructions to put together a machine that's constantly changing, and we end up losing control over it. Saying this now, it sounds so metaphorical for our musical career, which is really funny."
