i have translated this greek lyrics: 1// by looking at the english and turkish translation to understand the story. 2// by listening to the prosody in the video to understand the emotions better in the song. 3// with the combine of these elements i tried to use the best word-choice. 4// the next sentence "Η καρδιά δεν με βγάζει ασπροπρόσωπο" (translated as white-faced) contains a greek idiom that needs to be explained what it essentially means. Only this sentence in the lyric is translated different at each other-language-translation. This aforementioned idiom needs help. thanx.
