Ok this one is hard, I heard this song in 2012 it was played in a Youtube Playlist in Ireland during a party.
It's an elecrto song with a very calm beat, no lyrics as far as I remember but a syncopated sample of a woman voice that forms a melody with vocals during the chorus that goes: "Hee Hee ! Ah Ah ! Ah Ah!.
The melody is really relaxing though the beat is softly punchy (it's kind of a lounge style song, kind of similar to what Morcheeba could play back in the 2000's).
