well I will give you a sample
just something that starts relaxed , and continues and get's awesome you know
its a INTRO , introduction > so it's only something that says : Come in and watch the rest , you know? so it must be something relaxed , a start of the music
start is very important , if someone doesn't like it , they won't look at it lol , personally if music sux I won't watch the movie xD
so it's important , u see this video I gave you as sample , I listened 6 times to it , watched it only 1 time , music is awesome =) do something like that , it makes a video more interesting , more exiting
what ever it is 
it must be like > come on in , listen more music
