Hi Marte, I'm just a learner but I can try to correct you.

"I write Tibetan": ངས་བོད་ཡིག་འབྲི་ཀྱི་ཡོད།

"I speak Tibetan": ངས་བོད་སྐད་ཤེས་ཀྱི་ཡོད།

And I think I could write ང་ instead of ངས་ but both are correct in present tense.

I hope it helps you. :)

When I want some German songs, I listen to the radio FFH Deutsch Pur:

Mainly pop music, I heard Die Prinzen there once, but there is also reggae, rap, rock. I hope you will like it. :)
