I think that it’s an underlying Spotify issue for sure, namely that an album is often present as an explicit and censored version. But I feel like Zotify should be able to deal with this.
While songs show up in Zotify with the [E] you usually just see multiple copies of the album without any identifiers. One of these will be the “real” album, but there doesn’t seem to be a way to filter the others.
Somewhat ironically, both of those things would actually require a license as opposed to ownership
