Blue (Da Ba Dee) was released by Italian Eurodance group Eiffel 65 in 1998 and became a worldwide hit in 1999, reaching number one in many countries. Its nonsense-syllable chorus and story of a blue man living in a blue world made it easy to remember across languages. The song later found a second life online through early viral videos, remixes, film placements and memes. Short clips of the hook still circulate on soundboards because the melody is recognised worldwide within the first few notes.

A short clip of the da ba dee da ba dae hook from Eiffel 65's Blue, used in edits, memes and reaction videos for a playful nostalgic pop hit.
The sound is a brief snippet of the famous da ba dee da ba dae vocal hook, sung in a processed, slightly robotic voice over a bright electronic pop beat. It captures the most recognisable part of the chorus, instantly cheerful and a little surreal. Played on its own it works like a musical punchline, turning an ordinary moment blue, silly or dreamlike. Viewers recognise it immediately from childhood radio and early internet videos, so even two seconds is enough to trigger nostalgia, a smile and the urge to sing along to the rest.
