We’re not talking about the same thing. You’re talking about the HD/Fury feature allowing you to play your own music directly inside the game.

And here people are expecting Omega Collection to pick up the sound input from another application playing music outside of the game.

It has been known from the beginning that Omega Collection wouldn’t have the custom tracks feature, since Sony has a new policy on music rights on the PS4. It was confirmed half way through development as well.
