Farewell songs

I have a few songs in my library that represent parting with or saying goodbye to something. One of these is "たんたんたん" (Tantantan) by Mass of the Fermenting Dregs, enclosed in a 192kbps MP3 file. One of my favorite bands, Mass of the Fermenting Dregs (called マスドレ for short) made their debut with a self-titled EP (sorry about the low sound quality) and went on to release another mini-album and a full one before they came to an abrupt stop in 2012 ("they" is an overstatement; only one of the original members remained by the end). "たんたんたん" is a farewell gift from the last member, Natsuko Miyamoto, and she wished for the song to be spread across the world. Here's a link, since YouTube compresses data and lossy-to-lossy compression is something that I would rather not risk.

Another Japanese artist that I like, Kinoko Teikoku (きのこ帝国), made a five-song EP with songs focusing on the concept of saying farewell/losing things. The band, around the time they made this EP, were in a transitional phase. Amid their increasing popularity, they also were in a time when they were experiencing changes in their human relationships and environments. I remember listening to this plenty near the time of my high school graduation, which is one of the reasons why this EP left a really strong impression on me.
