I need a song thats quite dancy and builds up from virtually nothing
to a climax (with a dip just before). I need this for a launch of a
product; like for a countdown. I'm going to have a video to this music
with a timer counting down then when it reaches 0 the music climaxes.

Any suggestions grateful

its not exactly 'dancy' (more headbangy), but rammstein's self titled
song (rammstein) does sloooooowly build up to an amazing climax with a
slight dip just before.  it can easily be found on any filesharing
network or on their album Herzeleid.  this will definatly appeal to
many adolesent males.

Yeah I know the one; good track shame it won't fit this use. It's for
a nightclub- dont think it'll go down that well.
Thanks Anyway

Would something Apollo 440's "Time is Running Out" work for you?  More
of a count-up than down tune but it seemed well placed in S.W.A.T.  
Might work in a club atmosphere if hasn't been done t'death already.
