>> Absolutely. You're processing publicly available RSS feeds for personal use, which is protected under fair use. We also share revenue with creators based on your listening, so they're fairly compensated.

I dont think you can hide behind "it is publicly available, so I can take it and sell it". That's not fair use. You're redistributing it, and specific licenses come into play.

This is an interesting idea indeed, but not sure whether you'd be able to make a sustainable business out of this.
