Well there 's an aspect that will affect the outcome. First off, Sony decides to release a NEW ALBUM (count as 8th) with previously unreleases material. This means that in every Alejandro's releases ( and like other artists) there are songs that never make it to the final production. Sony decided to those remaining songs of each release, compile them and make a brand new album. All with lefover songs Alejandro Fernanadez left in each album.
In my opinion ( since I don't know how this will turn out) Sony should only make new albums based on officially released material, NOT UNRELEASED material. Still, it would be interesting to see the contract terms ( eg..does the contract states that every song are owned by Sony, even if they are not released?).
Come on, those are songs that were left out, that maybe Alejandro Fernandez could use later ( with his newer universal contract).
In my opinion, I think Sony is screwing this one.
