These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Archive Panic: The secondary importance of albums has made it almost impossible to acquire nearly any artists' original Motown albums produced in the sixties.
Several years ago Universal Music's "Hip-O Select" imprint began a series of box sets (each containing 4 or 5 CDs) devoted to collecting the complete Motown singles alone; there have been more than a dozen such boxes issued, and the series still isn't finished.
Dead Horse Genre: The trope page suggests that Motown is the exception to this trope in the manufactured bands category, but there are probably more than a few listeners or critics who dislike the formulaic, factory-like Motown production process.
