Methinks you lazy or possibly a thief
Who cares if there's a full English translation in the author's note? I'm not going to be looking back and forth between two windows while watching the animation, so unless I felt like memorizing the lyrics (or in my case had seen this a number of times beforehand so had a good idea of what was going on) the author's note didn't add to the animation in any meaningful way. To be honest the fact that there was some English in the animation and you had the translation in your note, but didn't bother to include it in the animation makes me think you didn't actually make this, merely ripped it from somewhere else (like 4chan).
