Musical challenge

On sunday I will be going to a Working Equitation competition with Rowan. During the dressage test you are allowed to have music to accompany you. It will be purely background music (not choreographed like in musical kurs) but I do want it to be suitable music.

This is where you come in! I could use some ideas.

 I need something about 6:30 mins long (or longer). That has some rhythm to it, but not too heavy. and that is interesting, but not  overpowering.  I have some nice film score music, but a lot of that is very building toward a crecendo, which doesn't fit the dressage test. A big moment in the music looks silly if I'm just walking around the ring at that moment.

Something Welsh celtic would be cool, as apparently the jury like themes (& hoss is a Welsh Cob) but I'm by no means wedded to that idea.

Unfortunately it turns out to be a lot easier to find music that clashes with the riding than music that complements it!

I'm currently thinking about parts of the Band of Brothers soundtrack, Brian Eno, and Enya as fallback (a lot of Enya has the right sort of deep rhythm without overpowering. Unfortunately I've not seen a track of hers that's long enough, and stitching together could get ugly)

If anyone has ideas I would be very happy to hear them. If possible with youtube links for easy quick listening.
