During an interview given for music magazine Any Music, Maki and Yusuke stated the title track was written as a song meant to inspire those who are depressed during the winter months. Maki stated that she and Yusuke wrote the title song with an inspirational meaning because the hardships a mutual friend was undergoing at the time. Yusuke went on to say that he wanted to have a more upbeat song after their previous single, Dreams, which was a song about the sadness of breaking up and felt that his friend's hardship gave him the inspiration needed to write the song.

The music video for Amazing opens up to a miniature carousel being played. As the music begins, the band is shown on an empty stage and Maki begins to sing. The rest of the video showcases the band playing the song throughout an abandoned theater.
