How can the "Listen using Zvooq" button for a Facebook fan page be made using https://www.facebook.com/davidgarrettofficial
as an example ?

Answer 1

1. Your page must have more than 5000 subscribers
2. There must be a group on a music site (Zvooq, Spotify, Rdio, etc..) with the same name and existing tracks
3. Further instructions from the documentation, in English, I hope you understand:
From your Page:
Open the admin panel.
click help.
Select Get More Features. This option will only be available for some Pages.
Confirm that you're the official representative of your Page.
Click Submit.
Someone at Facebook will review your request. Once approved, you can edit the music catalogs on your Page

Answer 2

Thank you.
