I just realized yesterday that B*Witched made the cover of "Mickey" that was in Bring It On. I don't think that movie did as well in the UK, but when it came out in the U.S. it was more successful than Clueless had been at the box office
I do remember their music being played on Disney Channel a lot in movies like The Princess Diaries, Life Size, Smart House
oh and I liked the song they had on the Pokemon movie soundtrack too. I have so many great childhood memories tied to their songs
