Regarding r152735

Why is this tag getting unaliased? I think it either should be aliased or removed, but not left existing with 0 works assigned alongside with a new one for this song

t166.1: My bad, I thought deleting an alias would make it disappear entirely, but it turned out to convert it into a standalone tag instead. I was not previously aware of this rule.
However, I'd prefer to remove this alias, since it is actually not the correct name of the song according to the information I have consulted. I will bring this issue to the editor's attention, thank you for your notice!
