one of my favourite songs is 'farewell transmission' by songs: ohia (jason molina). https://www.youtube.com/watch?v=malJUMz2A9Y It is very famous so probably you have all heard of it, but i think it is special because of the yearning, wistful feeling that it seizes upon so especially well. what are other songs that elicit a similar yearning... a sense of missed possibilities, and a brighter past?
