Music considerations

I've decided that I think I would rather have a song that is instrumental and one that isn't very well known. This is because I think it would look like a music video if the song had words, and it would be more effective and hard hitting if it wasn't a popular song.

I have considered the following:

The Cinematic Orchestra- To Build a Home
Bon Iver- Flume
Bon Iver- Skinny Love

So far, I have decided on The Cinematic Orchestra- To Build a Home because I like how it is piano based and starts of very simple, and has a dramatic build up. I think this song is going to be the most effective and fitting. I will be using the instrumental version.
