If you are adding a release, look at the associated labels of that release. If it has Sony Music Entertainment as a copyright holder or similar credits and a-tisket or API is showing a release date before June 22, 2021, please use a date after this (if found) or just 2021. This is when Sony Music purchased UMGs interest in Alamo Records. If used with another label, i.e. Interscope, Geffen, Quality Music, etc., and doesn't have Sony Music Entertainment as a copyright, it might still be original date.
