I made a few changes and am finally satisfied with the translation.
The video will be put up later. One of the most important things that I had to change was the way I interpeted どういう気持ちで. I had it as "What did it feel like," when this is actually asking about the emotional motivation for kissing. The rest are little things that I felt made it read better.
I wanted to ask you, how much truth do you think there is in this song? It doesn't seem like a song that was just made up from her imagination. There are some things in it that match up with things that are known to be true about Shiina, and I heard that she cries sometimes when she sings it. Do you think that this song is about her and that none of it is made up?
