"So Easy" is a song by Norwegian duo Röyksopp, released as their first single. Originally it was released in 1999, with only 500 copies made and distributed. Later it was re-released on Röyksopp's debut album Melody A.M.. "So Easy" contains instrumental and vocal samples from a 1960s cover version of the Burt Bacharach/Hal David song "Blue on Blue" (wrongly "Who are You") recorded by a Swedish vocal group called Gals & Pals. (It had originally been recorded by Bobby Vinton). The sampled lyrics are: "Blue on blue, heartache on heartache/Blue on blue, Now that we are through."
