Off the Wall [SEP] Introduction
"Off the Wall" peaked at number three on the "Billboard" Top LPs & Tapes chart and number one on the Top Black Albums chart, staying at number one on the latter for 16 weeks, and was an enormous critical success. Five singles were released from the album. Jackson wrote three songs himself, including the "Billboard" Hot 100 number one single "Don't Stop 'Til You Get Enough", which was Jackson's first solo number-one single since "Ben", seven years prior. The second single from the album, "Rock with You" also peaked atop the chart. With the title track and "She's Out of My Life" reaching the top 10 of the chart, Jackson became the first solo artist to have four singles from the same album peak inside the top 10 of the "Billboard" Hot 100.
