Annyeong!
I don’t know where the Plex agent gets music metadata from, but the descriptions for albums and artists and such don’t seem very neutral or indeed appropriate for a music library. In fact, they hinge more toward the ‘unduly critical’; the vast majority sum up as “this is a terrible album/artist”. The writer may have been inebriated. The descriptions should be just that, not ‘reviews’. It seems very unprofessional.
I think there is a way to change this within a server’s setting (I’m not sure though), but my point is that whatever agent is being used should have its use discontinued as an agent and a more neutral agent substituted (much like those with very neutral descriptions for video media), or at least not be used as the default music agent anymore.
