I think the best thing about this is probably the title. It really knows how to be unique. The song isn't one of your best, but is still well done. I think it may be because you are just letting your heart out so much about an instrument. You've discussed nearly every sad subject before. Why not write a sad song about an actual instrument?

While not that strong, it's great to try something different. It's also nice how it ends on such a soft note. You seem to be a bit more sad than usual in this song. You might want to make something with a different tone. The instrumentals are nice, which I think uses a guitar.
