Neato effexy thang & a generally entertaining piece of eye-candy, but what I like about it most is how it's fun to read into. I think it's supposed to show a video-editing battle between Light & L.
Great lyric-sync & dramatic mood. Expresses the general feel of the anime and the thoughts of the characters very well.
Another example of powerful lyric-sync, especially when it comes to matching the intense emotions of the singer.
