DDR lyrics
Yeah, so I was playing Dance Dance, and was doing one of the many J-pop songs, where I have no idea what they're saying XD But, then I thought I heard a "tenshi" in there o-o So, I looked it up, and I was right! The song was iFutureList performed by Akira Yamaoka. I went through the words, and was pleased to find others I knew, including "tsubasa", "tsurugi", and "megami".
On the site was a list of other songs by him, and browsing through it, I found Room of Angel!
insaneladybug, I know you've probably mentioned the singer before, but I forgot, and so was surprised to find that song there. I went through the lyrics of that too, and found the origin of "Always You that I Despised". I just thought that was the strangest coincidence, that the song I happen to look up is related to the songs Ladybug based her titles on.
