Who should authorize an album's digital distribution? 

All content that is sent to the channels and, therefore, is distributed for commercial purposes, must have the approval of its owner(s) (as stated in Article 19 of the Intellectual Property Law).

Still, the requirements may change depending on the type of content:

• If it is a release (album, EP or single), regardless of who owns the copyright (lyrics and music), for digital distribution only the authorisation of the owner of the master or who has control over this.
• On the other hand, if it is a distribution of a ringtone or a karaoke version, it will be necessary to have the authorisation of the beneficiaries (authors, publishers, etc).
