If one selects the tab: "BROWSE" indeed all the types of ads including music recordings are together.
(or the browse tab in categories)
I had never noticed it until the op asked this question. Since I could not think offhand how the op would find such a combination.
Then I thought of 'browse'.
The solution is to not use browse LOL
Up to this moment I always used the tab for the kind of component I was looking for. IE Amplifier: solid state.. etc.
If one is indeed looking for the very latest of ALL (but only equipment) adverts.. I guess the difficult task of being forced to look at music ads might undo some folks.
(IMO most music for sale ads here are way overpriced anyway.)
