“Gimme! Gimme! Gimme!” has a secret pop-culture legacy – its famous opening riff is so catchy that Madonna personally requested permission from Benny & Björn to sample it for Hung Up in 2005. ABBA had never allowed a sample of their work before, but they loved Madonna’s idea and said yes. The result? One of her biggest hits of the 2000s—proof that the groove can fill dance floors across decades.
