I recently watched 13 Going On 30 again (the last time I saw this movie was probably around my own 13th birthday) and I got to say I liked it more than I did last time. I not only liked the story very much, but also the music. In the movie they seem to listen to quite a lot of old songs like Love Is A Battlefield by Pat Benatar. The main character Jenna also listens to Jessie's Girl by Rick Springfield a lot. Both classic songs!
