And then add in all the manic merges that seem to happen. Some members of MB merge based on lengths and AcoustIDs which in theory is fine, but in practice means errors like this get built into even more complex errors.
Also add in that when someone is adding in a Compilation disk like “Bond Film Theme Tunes” it can be very boring, complex and time consuming to link all the tracks up correctly to the correct recordings. Especially for a noobie. The GUI is too small to be able to really understand the differences between version of a track in that window, so “close enough” can often occur. Leaving a compilation pointing to the wrong version, and then attaching its AcoustID to that wrong version. I know I will have been guilty of that in my early months here.
IMHO there is no clean way out of this without, as @psychoadept suggests, someone having to physically work through disks. Maybe we need a “certified” AcoustID system? Some kind of update where editors with OCD are allowed to “certify” that their data is coming from a CD and only a CD/vinyl/Original?
Something to add some quality weight to certain AcoustIDs?
I don’t look at the AcoustID site much - but do notice that when a name of the track is included then a counter can lean towards which version it really is. BUT that then drags us back to the same old issue of some people just not attaching the correct tracks…
Certainly the worst tracks are ones like this. A one hit wonder of a track that spreads all over the place to maximise cash-in. And then it is piled into film compilation disks. And Bond disks. And many places that really won’t care which version they have as long as the name is correct. Try reading the credits on those CD booklets and it is impossible to know which version you have in hand.
