I personally will to watch the opening or ending of a show of shows that I like by themselves,for example the spice and wolf 2 ending. this is obviously a little cumbersome at the moment. so why not upload a version of the clean opening and ending for shows, with the japanese lyrics and english translation on the video. so to clarify I am referring to the style that fansubbers, NIS, ANN and others do with the openings, instead of even episodes being in japanese and odd episodes being in english.
so to sum it up (hopefully clean) opening and ending videos for shows to be uploaded that have both the english and japanese on them.
