The Uncovering (of the Most Mysterious Songs)

 The Wagamama song & "?- LIKE THE WIND" have been reported 2 have been identified in the month of this post.

Another theory is that the "Fly away" track may B from a music library, which tend 2 B difficult 2 find the origin of. Especially the clue of "Audio Representative Associates"'s ambiguous, business center'd name. Whether it is used in media  would confirm a library'originating status.  The other clue is that the artists, vocalist remains anonymous. While this is but the case with "Wagamama" on a similar format, this is still a thought.

TMMSOTI/Blind the Wind/Like the Wind has lots of publicity under its confirmed title alongside the band behind it

The Akiba Tape might face a similar outcome when least expected.
