It spawned three commercially successful singles: "What You Waiting For?", "Rich Girl", and "Hollaback Girl". The latter reached number one on the Billboard Hot 100 chart while also becoming the first US download to sell one million copies. In 2006, Stefani released her second studio album The Sweet Escape. The album produced two successful singles: "Wind It Up" and the album's title track "The Sweet Escape". Her third solo album, This Is What the Truth Feels Like (2016), became her first solo album to reach number one on the Billboard 200 chart.
