Market Research?

I was in the audio section of the Unreal Marketplace trying to do some market research to see what type of soundtracks this community of developers liked however when I checked to see how many people bought a product all I could find was the amount of people who left reviews on a product. So is their a way to see how many people have bought a product in the marketplace itself, or is there a third party website like steam spy but for asset developers?

That’s probably Epic Proprietary information at a guess.
How long did it take before even Steamspy info arrived!
You could first look maybe at the competition that’s free.…texture-images…lly-free-music

In my humble opinion, the standard is pretty high there!
Overall, what you could do is start to offer niche ranges.
Alternatively actively start a thread / poll and ask people…
