High and light music must be analyzed as one field, not separate spheres.

Evidence

The diverse spheres of music must be thought of together. Their static separation, which certain caretakers of culture have ardently sought - the totalitarian radio was assigned to the task, on the one hand, of providing good entertainment and diversion, and on the other, of fostering the so-called cultural goods, as if there could still be good entertainment and as if the cultural goods were not, by their administration, transformed into evils - the neat parcelling out of music’s social field of force is illusionary. — Theodor W. Adorno, The Culture Industry, 72

Categorization

• DEFINE: A methodological instruction — read the whole cultural field together — essential for the reader who wants to run this analysis on new objects rather than the separated halves.
• XREF: The claim that ‘the cultural goods were not, by their administration, transformed into evils’ connects to the earlier ‘free time is administered’ thesis — administration transforms value into its opposite.
