I really like this Mongolian singer B.Azzaya's M-pop style music video. Such comfy song. She has been singing and playing violin since she was a little girl. Her voice is super cute.

This is another, pop style song where she sings about her birthday.

I think this Uka's music video might be the most viewed M-pop music video on youtube at the moment with over 6 miллion views.
