If you want an example of a straightforward TV series music archive, check out the Network CDs of The Prisoner. Uttlerly unlistenable without major home editing.
Interesting. What makes them unlistenable?
Well, they present every single cue in the library in order of recording, not in any episodic order. There are tracks and tracks of odd guitar strums, multiple takes of slide whistles, a rejected opening theme in three parts - again not in the order they would be musically, but in the order of recording. Many cues have the sound guy announcing "Prisoner 1 take 3" or whatever. There were about three composers, the first being Robert Farnon who had his music replaced. Wilfred Josephs, Farnon, Albert Elms and Ron Grainer's work were all separated and really, it's just a hash. Farnon's compositions come across like someone experimenting with sound. It's really a mess. Later Network CD sets were organized by episode.
I get that with multiple composers creating music used for a single episode is an issue, but there had to be a better way to organize them to make it work on an album.
