Under "All items" a total of 9,402,106 results are found. If I add the number of results in each subcategory under Music (left frame, under "Categories") I get a total of only 7,039,350 results. That means 2,362,756 listings in "Music" are not categorized in any subcategory, and as such not browsable unless you want to go through all the nine million plus results (and you don't!). This also means any vinyl record sold which is not listen in the "Records" subcategory (i.e. among the ≈ two million results mentioned above) will not show up on e.g. Popsike, even if it sells for $1000, right? I'm guessing Popsike only searches in the "Records" subcategory.
So, question is: Am I correct on this, or am I missing something?
