Music for our "Motion Picture"

At the moment we were recommended by our teacher to research the artist "Moby" who produced the theme song to The Bourne Identity called Extreme Ways. Apparently he produces free downloadable music for small non-profit films that are in need of tracks to accompany their film. VKLC productions therefore decided to create an account with his company and began searching for possible songs. We all briefly discussed beforehand what we each heard in our heads when looking at our footage. During this discussion I remembered something I once read from the book "101 Things I Learned in Film School" -

The music you hear in your head during filming is probably not the right music for the  film.

"If you have a 'perfect' song or score in mind while writing a script, prepping, or filming, the moment you match it to the edited footage you are likely to be disappointed. The image and the story want what they want, not what you want."

John Williams, composer, five-time Academy Award winner

Surely enough, I'm starting to understand this, and as we went through the individual sons one by one, I started liking what we had found. Despite the fact that it was different to what I had in mind. I'm not sure how everyone else feels about it though.
One thing we all decided upon was that no matter what musical choice we make, we wanted the music not to attract too much attention to itself, considering we also have another two layers of additional sound- The Voice Over and the diagetic sound of the underground. We think if there's too much going on, it will sound too hectic- and too cramped to focus on what the Voice Over is saying.
At the moment from the list on the website-  these are the songs we have chosen:

• Wait For Me
• Isolate 
• Ghost Return 
• Wait For Me (ambient)
• Sighted
