sythyry | OOC: Sythyry Music?

I've got a decent playlist for Sythyry-writing. But I'd like to expand on it a bit.

So, can you recommend music that you think would encourage me to write more Sythyry?

Tracks tend to work well if:

They don't have English lyrics.
They are fairly upbeat and energetic.
They suggest Sythyry (or World Tree stuff), or a mood you'd like to see more of in Sythyry, or something like that.
They are available as MP3s on Amazon or iTunes, or you can send them to me, or something.

I've got the LJ handle of the person who told me about a track attached to the name of the track in my playlist, so I kind of think of them as "Scorpion Frog from otter3" and so forth.

Thanks very much!
