On Twilight’s first soundtrack, Robert Pattinson  featured his song Let Me Sign, which was played during the fight scene between Edward and James. Many of the actors and actresses within the Twilight series are VERY musically inclined. Now Jackson Rathbone, AKA Jasper, may showcase one of his singles with his band 100 Monkeys on the New Moon soundtrack. Although many know that Muse and possibly Kings of Leon will be featured on the New Moon Soundtrack, I can’t help but wonder what other Twilight cast members may contribute their singing talents.
