This song was originally made by Suga Shikao and later given to SMAP. SMAP made a hit out of this song, few years ago. I like this song out of all the other SMAP songs as well as it made me start to listen to music by Suga Shikao. I love this song and when I'm in my bad times, I unconciously start singing it to myself. Anyways, music is great. It gives out not only your feelings in the lyrics but also gives you alot of powers during your good and bad times. No wonder, I can't stop listening to music. by the way, I prefer this song sang by Suga Shikao in an acousutic version.
