[Kriptc06]

Russian, sounds quite familiar to me, my grandmother spoke it, so I feel every time I listen to it I can almost understand, but not really.

Romanian, it's quite unique and sounds very cool, 50-50 between familiar and foreigner as it is a romance language, I self taught most of what I know, as I don't ever remember my grandmother mentioning about it.

Italian I like the rhythm and can read/understand most of it

English, Irish and Scottish variants, these are bloody cool, love hearing them, although challenging at times.
