Decipher the Layers...

Underneath...whispers invisible...
Plot your course, but beware...

Seek ID3, within lies the truth...

Search not for what is present...
What is expected...what is seen...

Gather...exchange...subtract...
Syntax differs, bevies persist...

rnEPv9.php...the unlikely oracle...

One may ask, one may tell...
Where the end begins, the code will swell...

Venture forth, my seeker...
