Have you ever listened to Angela Aki's Japanese song. I found it on youtube and felt that it's a nice song. She's not only a singer, but also a pianist. Perhaps, she composes songs, too. But, this song, "TEGAMI 手紙" is a the Romaji of Japanese which means "Letter" in English. The song is so inspiring and also a song for motivation. Read the translation on the video carefully. I embedded two videos here, the song and the music box version. Enjoy them!
