Take a listen to Ciuleandra:

This is performed by a Romanian singer, Maria Tanase, who lived decades ago. She specialized in folkloric material, and was very popular in Romania. I'm never sure how good a source Wikipedia is, but here is their article on her:

Lastly, here is an haunting tune she did. This is from Romania, but I believe it is a Rom (Gypsy) tune, rather than a Romanian one. (There is a very nice dance to this, but while I learned it once a while back, it didn't stick enough for me to reach this.)

And that is your folk-dance tidbit.
