Music for trailer

For our trailer i want to include two types of music:
The first of which i want is a slow piano, then when the action starts i want a fast drum beat and some guitar so it will excited the audience.

Examples of these are the start of the song Bulletproof heart by My Chemical Romance, and for hte faster part a song called Warrior by DIsturbed

For copyright reasons I can not include on blog or in film so will be creating my own based on these as now inspiration

we are going to Sony Acid or if that fails or takes to long to create our own music we have a back of http://www.jamendo.com/en/ where you can download free music
