I recently came across Christian Ronig, a German guy who seems to love rebetika songs, i.e. Greek songs from 2 generations ago. He has translated and modified some of them to a different style, which still captures the original essense. It is quite interesting to see what a person with completely different influences sees in a different culture. I think he does a great job.
He has an album named “Greece is mine”, here is one of the songs (morning in minor). Youtube has some more which might brighten your day.
