I object...
It seems like it would be better if you used this new name in the description of the categories rather than name it. I think the way it is now is okay, the new name seems unnecessarily long... Plus IMO it doesn't sound like it mixes well with the categories on an average Song page (Original Songs, Japanese Songs, Songs featuring Hatsune, Hall of Fame, Songs that have been featured in a concert). The length and the way it's worded just seems weird to me. This seems like a good idea but I honestly prefer the current name of the categories.
but this is just my opinion(^▽^)/
