A song themed around letters. A popular letter song.
Compared to the past, we write and receive letters far less often nowadays.
Still, letters have their own charm, and I think they’re a wonderful way to convey your feelings.
Precisely because of the times we live in, there may be many things that come across better in a letter.
This time, I’ll be introducing songs with the theme of “letters.”
There are many kinds of letters—thank-you notes, love letters, letters to your future self—so there are all sorts of “letter songs.”
Just hearing the word “letter” makes it feel like something filled with heartfelt emotions, doesn’t it?
Since there are letter songs for many different situations, I hope you’ll find a favorite.
