Please understand me. No harm intended.
I just launched this to test an idea. And a lot of people seem to have a similar demand for this type of narration service. I'm not exactly sure how to make this happen, but i'm just testing an idea.
If you were building a service that solved this problem (way too much written content, not time to read, so let's listen instead) — how would you go about it?
As I just said to you on Twitter (https://twitter.com/garybernhardt/status/874884772174196737), this is blatant and willful copyright infringement. Maybe the owners of the other works that you're currently infringing on don't care. But if you continue to do this, you will eventually encounter someone who does care. And if it goes on for a while, and then they notice, and then they sue you for lost revenue (which you will probably settle extremely unfavorably because the infringement is so blatant) then it will be neither enjoyable nor profitable for you. The American legal system doesn't care whether "no harm [was] intended" if you are depriving people of the use of their copyrighted works.
Pull all infringing works from the site temporarily (which means every recording). Email the authors of the infringed works, asking them for permission. Never post another recording without permission. Maybe it will be an awesome service.
