I for one would only be thrilled by A BEST 3 if it gets high-polished like the songs from A BALLADS. By that I'm thinking on new interpretations of the songs (remixes, but don't let them sound like mere "remixes") and a whole new song like "part of Me"
My favourite example on how that could possibly work is the ''Acoustic Piano Version'' of Dearest. The epitome of a song that was originally meant to be released as a remix and eventually turned out to exceed its predecessor (in my opinion) by far.
If A BEST 3 were to be produced like that, I'd be all in for it; else they can keep it and rather announce a new full studio or ayu trance 5 album
