Darling Nikki — Prince

Prince's 'Darling Nikki' didn't just push boundaries—it rewrote the rulebook for music censorship. The 1984 track's explicit lyrics, describing a sexual encounter in a hotel lobby, so horrified Tipper Gore that she co-founded the PMRC, which compelled the RIAA to introduce the Parental Advisory sticker in 1985. This sticker, applied to over 1,000 albums in its first decade, became a permanent fixture in music retail. Its legacy is measured not just in sales but in the millions of stickers slapped on records worldwide.
