Royalty rates are a completely different issue to the text shown when you are purchasing - but wouldn't you expect different royalty rates for different types of product/media as an artist?
As in, if I sell a vinyl record of your new single for $10 with your photo on the front and plaster it all over the record shops (with high distribution and manufacture costs) that the fee might be different than what I pay you for a $0.99 MP3 download (lower price but zero incremental cost), and that the $0.99 download fee might be different to the fee that the artist would charge for a live broadcast (highly dependent on licence context)?
Having said that, I was mostly talking about the difference between licensing and buying from a consumer's perspective. There are still a ton of restrictions which come with "owning" something, but those are just ignored by the author because those were laws passed by a legislature and not a license term by a private company.
