Blue (Da Ba Dee) was released by Italian Eurodance group Eiffel 65 in 1998 and became a worldwide hit the following year, topping charts with its simple synth riff and invented chorus. The song later found a second life online, where short clips of the chorus were reused in memes, TikTok edits, and blue-themed videos long after its chart run. Its nonsense lyrics made it easy to parody and remix, while its instantly recognisable melody kept it familiar to new audiences. That combination explains why it still appears in playful edits today.
