For downloadable software, the pitch was that instead of getting a single version of the software, you would now get all updates as long as you continued to subscribe, and that ongoing paymets would fund ongoing development and innovation.

## Modern day
Today we can listen to pretty much any track we like from any artist instantly by using a streaming service like Spotify or Apple Music or by finding music on YouTube. This is truly like a superpower and completely mindblowing compared to how we used to listen to music!
The downside is that in order to provide this service, all the music has to be uploaded to a central service that a company owns, and the company charges a fee to stream the music to users, giving the rest to the musicians. The free that the streaming services have been charging has been increasing ever since they launched meaning that over time, the wealth is being moved from the musicians who actually create the music to the companies who stream it and now have a monopoly on those streaming services. They also gatekeep who can get onto the services.
