Data Insight
Elvis Presley is the definitive 0% case in this dataset: the King of Rock and Roll never wrote a single song in his entire career. Every record, every hit, every iconic performance was built on songs handed to him by professional songwriters: Otis Blackwell, Jerry Leiber and Mike Stoller, Doc Pomus and Mort Shuman, and scores of others. His name occasionally appears as a co-writer on older recordings, but this is widely documented as a publishing credit arrangement imposed by his manager Colonel Tom Parker, not genuine creative contribution, and not reflected here. His catalog is a monument to interpretive genius: what Elvis brought was not composition but transformation, taking other people's words and making them immortal through performance alone.
