Non-metal Albums on the site

I don't know if we have covered this before, but I was wondering what the criteria for the inclusion of non-metal albums on the site is. The reason I ask is that the UK band Money who issued only one album, "First Investment" which is deemed as non-metal have it included, yet metal gods Judas Priest's debut Rocka Rolla is not. This just feels all kinds of wrong to me, so I have to ask if there is something I am missing.

The reason a release will be added to the site as Non-Metal is if there it's one that sits between other metal-tagged releases in a band's discography Sonny. That wasn't the case with "Rocka Rolla" as it preceded their metal albums & is well known as more of a hard rock record. In the case of the Money album, that was added to the site as heavy metal due to the NWOBHM tag on RYM at the time (Note: the majority tag was Hard Rock but, tellingly, Heavy Metal had been downvoted). I made the executive decision to alter the tagging after hearing the album because it's nothing like metal & the Hall of Judgement would never produce an outcome with such an obscure release. We don't generally delete releases like that, although we probably should.

Ah, ok. I get it now.

That's kinda my feeling about bands that were added to the site as metal but then became deemed non-metal, like Sky Eats Airplane. That was at the time when nintendocore was thought to be a metal genre, until we made the consensus that it is not. Although there is the need for that band to be gone from the site, I know you don't generally delete such releases, and part of me feels it should at least stay for some historical value.
