"Billboard" credits Clarkson for landscaping the core sound of mainstream pop music in the 2000s to an uptempo dance-oriented sound with the release of "Since U Been Gone" and the singles that followed it. The album's producers also came into prominence due to the album's success. Dr. Luke, who was the house band lead guitarist for "Saturday Night Live" at the time of "Breakaway"s release, has credited "Since U Been Gone" as his first big break. Max Martin, who had already found major success as a music producer in the 1990s and early 2000s with, among others, Britney Spears, Backstreet Boys and NSYNC, achieved more prominence due to the success of "Since U Been Gone" and "Behind These Hazel Eyes".
