 Of course, nothing prevents a CMS to generate this file dynamically, making this way simpler for users. But we
 wanted RadioManifest to be deployable as _"just a bunch of static files"_, as a way to increase early adoption.

+Almost. While `/streaminfo.json` is clearly valuable data, we wanted to account for more usecases:
+ - A radio should be able to list more than one URL for streaming. This can be for load balancing reasons, for
+   example. M3U are a simple way to achieve this.
+ - A radio can (and probably should) have not only more URLs for streaming, but actually stream different
+   versions: different qualities, different codecs, etc. It is reasonable that, as a user, you don't really
+   care about all those details: «Just gimme the audio!». However, your client could select the best codec for
+   your usecase. Or, it may let the user explicitly select "low quality, low bandwidth" for users that want to
+   save bandwidth. This is possible with radiomanifest adding multiple `<source>` elements, and is
+   unfortunately not with `/streaminfo.json`
