Soundtrack

I was looking through my music collection at home, and using the Internet as research, and I have managed to come up with about 5 songs which I can use in my project. I took the advise to check the soundtracks of 3 films similar to my own, and none of them have any of my songs included. I'm still unsure where in the film would be the best point to use these songs, but they are all rock songs, and are all fast paced, very in fitting with my genre.
