cultural_context_notes : "Released in 2016 as part of Bruno Mars's 24K Magic album, 'Chunky' is an electro-funk/R&B track heavily indebted to the sounds of The Gap Band, Cameo, and 1980s-90s new jack swing. Written by Mars, Philip Lawrence, Christopher Brody Brown, and James Fauntleroy, the song celebrates curvy women and unapologetic confidence, consistent with the album's broader nostalgic party-music ethos. Charted in the UK, France, and Portugal; certified gold in the U.S. and double platinum in New Zealand. Considered a deeper cut on a commercially dominant album."
