The studio album for Ummagumma is comprised of tracks where each member went off and wrote and recorded something on their own. Some issues show the member’s name next to the track; some list it as “featuring [member]”, and some omit the names and just give the standard writers credit. The question is whether the artist’s intent was to credit the tracks to band or to the bandmember alone. Is it a Pink Floyd song featuring X, or is an X song that happens to be on a Pink Floyd album, or should it be credited to some variation of “Pink Floyd feat. [a member of Pink Floyd]”, though I can’t think of any other examples where that would occur outside jazz.
The tracks are all registered at ASCAP as being written by the individual members, but performed by Pink Floyd. Some of the tracks had also been performed live by the band before being recorded.
The edits are to issues that use the “featuring” text, just to strip away the solo artist credits and revert them back to album artist credits, so we can discuss and vote on how they should appear.
