Suggestions for clearer tagging, towards deprecation of tags with cultural variations

As stated many times before (Previously: t33.3, t85.5, t98.1), it is a long-term goal to phase out tags like these.

song_recomposed_by_source introduced in t162.1 by @zatto is a good start, but I wanted to share some ideas that may work as tags that would have more universal understanding. I don't expect all of these ideas to be a good fit for our purposes, as I had drawn up some of these by examples I have seen and thusly may suffer from an incoherent scope if they were actually evaluated against a wider range of works. So I invite more discussions around these here. Feel free to drop in your own ideas too. If you think any of them are particularly good ideas then feel free to start championing them if none of the other editors object!

• 3D character animation, 2D rigged character animation (e.g. à la Live2D)
• Specially authored assets
  • Hand-drawn assets; hand-drawn animation
  • Themed authoring of original visual elements (e.g. own filming of a train while auditory samples come from announcements thereon)
• Story- or narrative-driven
  • Dialogue via 人力VOCALOID or otherwise.
• Has long non-musical segments
• Parody visuals (e.g. of an existing music video, recreated with swapped elements pertaining to the sources used)
• Abstract visuals (e.g. "motion graphics"-dominated)
• Commercial advertisement
• Original lyrics (as opposed to preexisting lyrics of a song)
• Instrumental augmentation (addition of musical elements not present in the song when it is not original song). Quite a lot of possibilities here that can be subdivided further.
• Reinterpreted time signature (triplets, slowdown, speedup, etc.)
• Has accompanying material (e.g. a booklet, a website, a blogpost, an ARG, etc.)
• Significant behind-the-scenes available (e.g. via a desktop video capture or a blog of sorts)
• Has repeating segments
• Loopable

  • Has Karaoke-style lyrics
• Has variations on different platforms/regions (e.g. Japanese version available on Niconico, English version available on YouTube.)
