Need a Dubstep song that will sound good if you overlay sound clips of speaking over it?

Hi there,

I need a Dubstep song that meets these requirements:
- Would sound good if you put sounds clips of someone speaking over
the top of it. (This one is vital)
- No singing.
- A few big drops.
- Catchy (i.e. with a good melody).

Many thanks,

Will.
