The full album is only available in Japan, and is geoblocked everywhere else. However, you can get around this by logging out of your Spotify account and using a VPN, which is what I have been doing. For a good free VPN, I recommend TunnelBear.
This method can be used for Apple Music and iTunes as well.
i dont know if there's any full list of saesangs for got7. i have a list i made of some mark antis on twitter (most of which are jjp stans) that's here if you want that, but i don't have any idea of a saesang list. if someone else wants to hop on i'd be happy to try to help compile that but i can't do it all by myself !!
