Yes, the raw AAC / OGG content would naturally break DRM. Spotify, however, has a ton of libraries that allow for you to write your own clients, which honestly allows for an "audio stream" for most purposes if you are able to run an OS. You can write a very simple CLI app that plays Spotify music for example, and Spotify's libraries will handle the DRM.
"Audio stream" to burn to a CD or a tape cassette? Yeah, that's not gonna be supported.
