Query: Bad bg music ruins every thing!

Ok,i saw this dvd for 20minutes,and i fell sleep right away!why? because background music is so boring that makes yousleep right away... I like all the forms,but i notice thattheir forms seems to me came from shotokan karate katas.i know that general choi said he studied karate in japan,but he never mention which style of karate! I think he is nothonest person,because he make storys about Takkyon and himself.. But as far as i know Taekwondo and Takkyon don't share anything common...
