Alan Jones from
Music Week gave the song a score of four out of five, writing, "Number one in Germany, this catchy confection combines Ital Joe's
Haddaway and
Dr. Alban influences with Marky Mark's streetwise rapping. A substantial hit." He later added, "This is an anthemic German production pairing the patois of Prince Ital and a more conventional Marky Mark rap with a big
chorus. Don't underestimate the potential of a record which has now been huge all over Europe, and consequently exposed to million of British holidaymakers." Miranda Watson from
Music & Media noted that the follow-up single to "
Happy People" "again blends the
Eurodance sound with
ragga and rap."
James Hamilton from the
Record Mirror Dance Update deemed it a "
Boney M-ish chant-along cheesy German smash" in his weekly dance column. Emma Cochrane from
Smash Hits complimented "United" as a "great dance track". ==Music video==
