context: The cover version came about because the original Fountains of Wayne song was often misattributed to Bowling for Soup. The song was misidentified as a Bowling for Soup song on YouTube and other video sites. In multiple interviews, Bowling for Soup bandleader Jaret Reddick has said that he regularly encountered fans at their concerts who mistakenly thought "Stacy's Mom" was a Bowling for Soup song. In 2011, they recorded and released a cover version of the song. Reddick said that by finally releasing their own version of the song, "I’ve basically just taken care of a large part of the population that’s been wrong for years, and I’ve made them right." Alluding to the mistaken identity issue, the cover art for the song release reads: "Finally you can say this is your favorite song by BFS and not look like an idiot!"
