Some interpretations suggest "Caroline" may also be slang for cocaine (similar to "Charlie" in English), framing the love as an addiction. Production and Musical Style
Producer Jimmy Jay recorded the song at the Opera Bastille with four violinists from its orchestra and used the first synthesizer ever used by the Beatles.
In the chorus, Solaar plays on the four suits (hearts, diamonds, clubs, spades). He identifies himself as the "As de trèfle qui pique ton cœur" (Ace of Clubs who stings/takes your heart), where "pique" also refers to the spade suit.
While Solaar delivers his signature soft-spoken, almost-whispered rap, the backing vocals are provided by the artist Melaaz. Cultural Impact
"Caroline" was a massive commercial success, peaking at on the French singles chart and remaining in the top 50 for 22 weeks. It proved that rap could be sentimental and intellectually rigorous, earning Solaar comparisons to legendary French songwriters like Serge Gainsbourg . The track has been covered and referenced by numerous artists, including Vianney and Zaho .
