Suitable music for paper prototype video?

I’m trying to find music to fit to the background of a simple paper prototype vid, any ideas what sites to find this sort of thing on?


Muji have a series of CD’s called BGM (background music), they are pretty minimal simple pieces with nice themes, there are 15+ BGM CD’s each with a different theme.
If I were making a video I would definitely use it. They use it in their adverts so you can get a sense of it here

Immediate Music do lots of trailer music:

so if you do a youtube search you’ll find heaps of themes that you’ll identify as soon as you listen:

pretty bombastic though, awesome to have playing in the car.
