Premise: Carole King . She is the most successful female songwriter of the latter half of the 20th century , having written or co-written 118 pop hits on the Billboard Hot 100 between 1955 and 1999 . King 's success as a performer in her own right did not come until the 1970s , when she sang her own songs , accompanying herself on the piano , in a series of albums and concerts . After experiencing commercial disappointment with her debut album Writer , King scored her breakthrough with the album Tapestry , which topped the U.S. album chart for 15 weeks in 1971 and remained on the charts for more than six years .
Hypothesis: Carole King does not perform music.
