17). Goodbye (I’m sorry) by Jamestown Story
Goodbye is a song from the album Broken Summer which was released in 2007. This is the only folk genre track in the list of songs about the suicide note.

The song is literally about a person who thinks nobody loves him and hence he is determined to kill himself. As the final stanza comes, the person bids his final goodbye to the world. This is a very depressing song.
