- The first release will prevail as the PRIMARY METADATA unless the arranger/composer decides to make some changes and it is considered authentic... right, Masayoshi Minoshima?)
Note: To know the context, look for the first release of Bad Apple (Lovelight album in 2007) and the current ones.

- The ARTIST will always be the name of the Musical Circle (Alstroemeria Records, EastNewSounds, Halozy, SYNC ART'S, C-CLAYS, IOSYS, etc...), never the arranger, the vocalist or another person involved in the production of a song or Album ... those names must be in Tags.
Note: This is specified exactly because sometimes arrangers/composers use songs that have already been released on compilation albums or something like "THE BEST" and by doing this people believe that the artist becomes the arranger/composer or the vocalist.
Note 2: Hanatan - Paranoia is totally incorrect.

- There are some Musical Circles that fall into the inactive category, but that doesn't mean they're irrelevant, as they were involved in some popular songs and many don't recognize them as the first Source.
Examples: ALADDIN, Mohican Sandbag, etc.

- ZUN is a sacred name, if it is not written in Tags you would be disrespecting the absolute creator.

- There are only two Direct tags (that could be considered official) for these songs... Game ver. and TV Size
1.1 - Game ver. tags will almost never have an official release in physical or digital formats since the vast majority come from the game itself (ripped directly from the game) and generally last between 1:40 and 2:00, more or less.
1.2 - TV Size tags are generally what artists and producers consider "Insert Songs," and the length and editing are different compared to the Game ver. or the full song.
1.3 - Other tags like Cut ver. or edit can be used unofficially as long as the editing doesn't match the points used in official versions.

- When it's a cover ("seeing Bandori and D4DJ") the anime where the cover is performed takes precedence... it's a bit confusing, but even though it's a cover, it's clear that it has a primary source (a previous anime or game), but you can't discredit the franchise that takes those elements, so in this case the original source will be the anime where they are using those elements, and the other metadata like the anime/game of origin could be specified in the "Description" or in Tags.
