"Whoa!" was the lead single released from Black Rob's debut album, Life Story. The song was produced by Diggin' in the Crates Crew member Buckwild. Released in early 2000, "Whoa!" became Black Rob's biggest hit. It narrowly missed the top 40 of the Billboard Hot 100, peaking at number 43, and reached the top 10 on both the R&B and Rap charts. To date, it remains Rob's only solo single to have reached the Hot 100.
In addition to Life Story, "Whoa!" has also appeared on the compilations The Source Hip Hop Music Awards 2000 and Bad Boy's 10th Anniversary... The Hits.
