I've been toying with the notion of making a page for "Artists of The FuMP" when they work collectively on a track - like this one and/or giving that name for FuMP albums. If we've learned anything from the "Funky Butts" fiasco, it's that everything without a stated ArtistID gets merged when coding quirks happen, making an immense mess.
In a case like this one, all the participating artists would go under 'facts'. Not every FuMP artist is on every collaborative track. Unlike the 'morning zoo' issue, someone can actually ask them what they want since some of you know/are "them." They can tell you themselves when the artist name's unclear.
The big rule for this (one that supersedes most other rules) should be a familiar one as it's one of the oldest on the site: "Artists can call themselves whatever they want." We just need to find out what that is.
No matter what we use as an artist name (we can always change it), the rest of the info about it goes under 'facts'. That's what the yellow box under the tan & grey boxes is for - adding details about the artist(s) and where to buy their works. Which goes where isn't nearly as important as getting all the info on the page and getting it right.
That's what a visitor who sees the page often wants. They come to the site looking for an old song they vaguely remember and we need to give them all the info we have about it. What goes in what box is something we can work out afterwards and change if needed. Correct info on the page comes first. If you're not sure, add it to the comments.
