Hooked on a Feeling was originally recorded by B.J. Thomas in 1968, but the version most people recognise today is Blue Swede's 1974 cover, whose rhythmic ooga-chaka introduction became its signature. The song returned to mainstream attention when it opened Guardians of the Galaxy in 2014, introducing it to a new generation and cementing its place in film soundtracks. Since then it has circulated widely in short videos, where its familiar chorus works as instant shorthand for nostalgia, optimism and playful confidence.
