"Breakaway"s singles "Since U Been Gone", "Behind These Hazel Eyes", "Because of You", "Walk Away", and "Breakaway" became worldwide hits and have become some of Clarkson's signature songs. Their successes prompted "Billboard" to credit her for landscaping the core sound of mainstream pop music as an uptempo dance-oriented sound in the 2000s. Furthermore, "Breakaway" established Clarkson as one of the four highest-selling acts of Sony BMG in the 2000s. Internationally, the album topped the music charts of Ireland and the Netherlands and became the world's 7th biggest-selling release of 2005, eventually being certified platinum in over 17 countries. To promote the album, Clarkson embarked on three international concert tours from 2005 to 2006: the Breakaway World Tour, Hazel Eyes Tour, and the Addicted Tour. "Billboard" placed the album 77th in the "Greatest of All Time Billboard 200 Albums".
