Music used in our thriller

we have considered the music that we would use for out thriller.We can not use any copyrighted music for our thriller so we have looked at alternatives free to use music sources.We have been introduced to the free music site MobiGratis, which provides non copyright music for non profit/student films.I have signed up for the site and now we, in our group are looking at what we Music we might use in our thriller opening.For the begging of the thriller we would like to have something upbeat as we are having people play football in the begging, when the kidnapping of our main character happens we plan on using something more dramatic.
