Priority can be 0, which means don't show in link list at the end.
name is replaced with 'identifier' and 'class'.
Identifier would be unique per song (UNIQUE constraint on song_id, identifier) and would be how we refer to a link in Markdown.
Class will be "youtube", "version", etc. It might even be a drop down and become class_id. In which case we'll need crud for classes. We could derive a CSS class name from this, perhaps.
I want
We currently have id, song_id, name, url, description, priority, extras (which is for stuff like YouTube aspect ratio, and/or start time, etc).
"description" is text that would appear in the link, but we'll want to style different destinations differently (e.g. add a spotify logo?).
"name" doesn't have a strict-enough definition for me to do what I want.
