The artist(s) for a particular post has been identified, but a second opinion is needed for verification. Can be used when the post is retrieved from a source that is not owned by the artist in question (ie. third-party_source, certain Twitter accounts, music albums, etc).
Do not use this tag if the source data already provides the artist's name. An exception to this is when the post in question consists of an artist collaboration between two or more artists.
