 ## Best Practices
 - Use an alpha-numeric id. Don't use dashes or hyphens; Uppercase characters *may* be used when appropriate.
-- Use `image/png`, `image/jpg`, `image/gif`, `audio/mp3`, and `video/mp4`. Files *should* be under 10MB and be of reasonable or tolerable quality
 - Declare metadata when available. If you do not know the original source, try to find it first.
 - Metadata **must** be accurate and not an artists rendition of the actual metadata.
-- Try not to use reuploads, remasters, or edits, as the source; Unless the edit or remaster is the actual media.
-- Sources *should* contain codec information; if you are unsure of what correct codecs to declare, do not declare any or ask for help.
-  No codec declarations are better than incorrect codec declarations. See [MDN](https://developer.mozilla.org/en-US/docs/Web/Media/Formats/codecs_parameter#basic_syntax) for details
-- Don't use videos where audio alongside AlbumArt would functionally identical. Lyrics videos are ok
-- All content *should* be hosted on Glowers Club. If you are not a Glower then your uris will be reuploaded if your Item(s) are accepted
-- Provide fallbacks for sources and previews when possible:
-    - `video/` *should* have a thumbnail preview.
-    - `video/` *should* have a `SQUARE` fallback preview for audioOnly and for when the agent does not support the provided `video/`.
-    - Animated previews **must** always have a `image/gif` fallback.
 - Items that aren't primarily music should be tagged with `misc`.
 - Use the `metadata-prefer-id` tag if the actual title would be too long, cubersome, or unrelated. i.e:
     - `slamtris`: Slamtris - Quad City DJs vs Hirokazu Tanaka *(cumbersome)*

 ## Format
 The `songs.json` format **is only intended for use for Glowers Radio**, and is effectively a living standard as a result. **Live data may change drastically without warning**
