Glad you liked the songs. I try to include a mix in my selections. I'm not trained in music - but yes - I really like the music that has something different to offer. I don't speak Kazazk, so I can't say much about the lyrics - I think I just really love the diction of the language though ;)
That Step Sons track is great! Another good folk ensemble from Kazakhstan is "Hassak". Though, maybe if you'd like a track from my Dec/Jan selection called Samgha.
