Much needed music

Hello there! Just a refresher if you need it, me and my group are making an intro to a thriller film. With that of corse we will need the basics of the thriller genre. We need to add the elements that make it actually a thriller. One of the most prominent things to insure it being seen as a thriller is the music. Thats such an important factor to our project itself. However we can't just use any song we want due to copyright. We will either need to use non copyrighted music or message/contact the owners of the song and ask for permission to use the song. This is extremely important because you can be sued over copyright. We were thinking of using music that builds heavy suspense. Luckily for use, there are many free music of that type on YouTube that we can use. I will also absolutely edit the audio we choose. I will edit it because it will need to match with the vibe and sounds of the film. I also plan to add sound effects to the audio when we pick the one we want. That make it more unique and match the story we are trying to portray. I really can't wait to finally pick everything for sure. So I can finally execute all the ideas that I have and want us to do. We are family soon so there isn't any need to worry about that too much. We have finally decided on a place to film and we are heading there on our psd day. I am so ready to get this done!
