Well as for Mongolian folk metal, Tengger Cavalry has an instrumental album, the Ancient Call. First song uploaded. It has a cool riff I think. The song itself is a bit much repetitive.

Folk songs. This playlist has some instrumental:

Fun thing, the latest seems to be a folk melody from Moldva (the visuals are Hungarian folk art):

It seems it isn't Csángó (Ceangăi how you call them), because at an earlier song it is noted that it's theirs:

Anyway the playlist should feature mostly instrumental songs played on various instruments, from dulcimer, through harp, to harmonica.

This one is Medieval music from the Hungarian Kingdom, not necessarily folk songs, although some are. I'm pretty sure that two - "Három holló" (Three ravens), and "Középkori dudamuzsika" (Medieval bagpipe music) - starting at 1:09 and 8:46 are instrumental. Perhaps others too.
