Colbert Bump: Their music is constantly being used in teen movies and TV shows. Even going back as early as Legally Blonde.
Face of the Band: Tricia. Anyone who's heard no more than a few songs probably doesn't even realize that they're not a Girl Group.
Misattributed Song: There are people who believe that Hoku's "Perfect Day" was performed by Superchick. And then there are some, but not as many, people who think that Hoku sang "One Girl Revolution." The confusion most likely stems from both songs appearing back-to-back on the Legally Blonde soundtrack.
