I've been discussing the issue, same as everybody else here. That's all I can do. I have no authority to make any changes or "apply" anything. I understand the opposing viewpoints, and I respond directly to other people's arguments and evidence, but I don't get anything like that back. If "type" isn't meant to imply structure and form, why is it only a list of structures and forms? How will this be useful in searches if a lot of instrumental music is filed under a different type? I asked those questions for the first time in my last post, and you're saying I'm just repeating myself. Jesus and Samsom have posted four times as often as me, and they're saying the same thing over and over too, why don't you go lash out at them?
Then somebody FIX it. Somebody fix the documentation. Fix the UI. Change the label. Write a page where every type is defined and explained. I have no power here, I can't do it. If I could, I would. But opening it up to whatever term anybody wants to throw in there is only going to make that problem worse.
No, if you can argue somebody composed a work to be instrumental, you can argue they composed it to be electric. They're both just simple descriptions of instrumentation. This piece is an electronic work, this is electric, and this is electroacoustic (and a "song" by your definition). In each case, the instrumentation is inseparable from the composition, but not from the structure. Any argument you can muster for "instrumentation" can be applied to these terms or pretty much any other descriptive terms. Unless we set logical boundaries, we have no reason to exclude any of them and the menu would include dozen of applicable descriptions for each work.
The most common jazz form is just the head, a series of runs through the chart for solos (chorus), and a repetition of the head, then maybe a coda, though I don't know if there's an actual common name for that form. That's what I hear in this: they run through the chart twice (the uptempo horns are near the end of the chart), then near the end they take a coda. Structurally, it's fairly similar to this piece, though the chart is longer. We don't have an entry for standard jazz form, so I'd follow the guideline and leave it blank: "Work types should only be used on works that specifically match the chosen type (not every work needs to have a work type!)."
Your turn: would you call this an instrumental? Would you call this a song (based on the last 5:45)?
