part of Me & Memorial address

[mellody]

I remember back then, there was a theory about these 2 songs...

Memorial address was a hidden track in A BEST 2 -BLACK-, it lies within part of Me, the only new track from the best album. That theory said why ayu wrote the song title "part of Me" with capital M, that's because it's actually "part of Me(morial address)".

Is it confirmed? Like ayu probably ever said something that the song is connected or that's just a simple theory? Because if yes, that would be so cool.
