Or to sum up, "your apps are sold from a store that also sells music. Niche app devs face the exact same problem niche musicians have faced for years: how to reach an audience without spending buckets of money."
Sure, but at least niche musicians can sell recordings of their music at more than a single store.
Or more accurately: "Isn't it hard to get noticed on the App Store? We made an app for that."
This is basically just an advertisement, not much useful information in it.
