This one was harder than expected. I seriously thought that there was a j rock song that I knew all the words to, but obviously there isn't - or maybe there is but I just couldn't fint it.. 

But I know one j rock song that I know almost all the words too, and all of the words in the chorus. That song is called Oblivious and is performed by the amazing Gackt ♥ It was the first j rock song that I deeply fell in love with, so this song means a lot to me.
