My personal opinion is that Musicbrainz Pickard is one of the best mp3/aac/flac/etc. music taggers out there. In addition it is also the official tagger for Musicbrainz. As more and more people are storing their digitalized music to NAS machines, it would be nice to have a good music tagger which also runs as a container within NAS.
I am writing this request with modest hope that someone within the great community can pick this up and create a Musicbrainz Pickard container on behalf of noobie like me. I will be happy to test and provide feedback by deploying it to my NAS environment. I run container station and exceptionally good container manager, Portainer, on QNAP NAS. I already run few of containers released by this community in my NAS, therefore being familiar how you expose environment etc. for linuxserver containers.
