I have noticed there is a tag for original arrangements, but I am wondering: how this is different from the remix tag mechanically? On a functional level, they seem to mean the same thing. Remix does have a kind of connotation that you're making the song more "hype", but strictly speaking this is not true to the meaning of the word, and I don't know that that connotative difference is enough to warrant them being two different tags.

I propose they be merged, unless there is a reason I am not seeing as to why they would be more different. If that were the case, wiki articles for the pair of tags would be requisite for sure.
