I think this would be a really nice resource to have.  I too have a lot of music DVDs etc which rarely seem to have very complete credits.  More generally, I always document any music used in films etc in my local database; (song titles using dividers as you have, plus writers and performers.)  I put these in the Crew / Music section.  I only add them to the Cast section if they’re credited onscreen, although I think you’re suggesting a more ‘complete’ record that goes beyond what's written onscreen.  However, I suspect there’re very few people who would wish to contribute to such a resource (given the level of research required), so like many good ideas it would probably not really go anywhere.  Certainly it wouldn’t ‘fit’ into the existing online database without some significant changes to the Rules.

More generally, I’m already of the opinion that DVD Profiler (like many things in life) has become too complicated for most new users to bother to learn to use properly; at least as far as contributing to the online database is concerned.  Less and less people seem to make contributions these days and those that do are mostly very experienced and have ‘grown up’ with the database as its use has been developed and the “what do we do in this case” issues discussed.  Sadly there’re now so many unofficial conventions, undocumented ‘rules’ and accepted (or often not accepted) ways of doing things that it’s become a nightmare to learn how to use properly.  The official Rules are simply inadequate nowadays, as there’re too many circumstances they don’t cover, resulting from a combination of new options being added to the database and the nature of films and their presentation etc changing.  I still make contributions but far fewer than I used to, as so often something I want to contribute seems potentially contentious or not clear.  Even the process of adding the additional music credits to my local database means if I have a contribution rejected, I don’t bother to resubmit it with changes, as this involves stripping out the dividers (which I add after making the contribution and that I don’t think can be hidden from contributions unlike non-standard credits), which I basically don’t have the time or inclination to do.

I guess I'd prefer to see a simple online database covering the basic, 'black and white' factual information, that we can then download and add to locally as we wish to, using our own personal 'rules'. The database in a mechanical sense seems very good, but too many things are now open to personal interpretation, which effectively makes the information it contains more unreliable in a factual sense.

So I guess I’m saying love the idea, but just can’t see it going anywhere.  I’d love to be proven wrong though!

Sorry, think I went off the subject a bit there.
