This is weirdly reminiscent of Monster Rancher for PS1:

>Although it is possible to acquire a monster in-game, the series is known for the ability to acquire new monsters using Compact Discs (CDs). Players can use any readable CD, and the game creates a monster using the CD's metadata.[6] Certain CDs would result in unique monsters: for example, Tecmo's Deception gives the player Ardebaran, a villain from that game,[7] and some Christmas music albums will give the player a monster of type "Santa".

Maybe this idea is a catalyst for something else.
