Here’s a riddle.

What is the difference between:

1. a service that lets you upload your entire music collection in order for it to be downloaded or streamed to you anywhere.
2. a service that lets you upload the DETAILS of your entire music collection in order for it to be randomly streamed to you anywhere.

The former involves reproduction and distribution of copies.

The latter involves no reproduction or distribution, only performance, and constitutes ‘webcasted’ radio.

So, if you want to listen to the kind of music you like wherever you are and don’t need particularly high fidelity, then the notion of the copy disappears.

And yet the same digital bits are flying around?

It’s just some lunatic who’s shoehorned paper and radio metaphors into the digital domain that keeps the emperor’s tailors in the lifestyle to which they’ve become accustomed.
