Music/Soundtrack

We have had a few ideas for the music theme and we are thinking along the lines;
a band named 'Example' and their song 'We came, we saw, we killed the crowd' this song we found was very fitting to the theme and stood out from all our other tunes.
This is a link to the site their music is on:

Although we would like to use this music and soundtrack we are still not sure whether we can use this as our overall music. In the end, we were not allowed to use this soundtrack so we created one of our own in garageband.
