It is not just a closing song. Any Ayu song is a song, no matter if it is Taskinllusion or any other song. And as an Ayu song always expect for something really fantastic, SPECIALLY if it is from a single, because I know Ayu has the potential to make super incredible and fantastic songs almost 100% of the time she releases something new LOL But I still haven't listened to the whole "Greatful Days" song. I really didn't like the preview but there's a chance I might like the whole song. That happened the first time I listened to July 1st as well. And the preview was a **** but the whole song was really good!
