Self-liner notes by the two creators of "Thinking of You" 15MUS Today, my priority was to do what I had to do. Every time I stopped, I was thinking more and more "for what? There was a feeling of wanting to make it happen, and I was the one who sang to feed on what a shitty gut feeling I had. But thanks to the many people I've met over the past years, I've been able to turn another feeling into a driving force. I am now able to sing with a gentle heart. Please listen to this song while thinking of the people who are important to you. You will find your own solution to this song. Seiji Yamaura I created this song focusing on guitar phrases that fit the chords that 15MUS came up with. The important point of the song was to create a sound image and lyrics that would allow the listener to feel the changes in the environment, such as marriage and changes in the town where I lived. I think there are times when we feel the frustration and apathy that we usually feel somehow, but I made this song so that we can be positive by having someone or something important in our lives. I hope this song makes you want to contact your loved ones after listening to it. My favorite lyrics are the ones about buying shumai from Kakiyoken.
