If you just install 8.x-2.1 you'll get a program content type which you can add fields to and create views for. You can schedule those program on a schedule grid.
There are limited options for customizing the look of the schedule and using the scheduled data in views. That is being fixed in the upcoming 3.x version.
Creating the audio content type and views for that along with podcast views can be done. But the Station module currently doesn't provide in default configurations for those.
There is no functionality for playlists.
What I mentioned overall is still the goal. 8.x-2.1 is intended to be a direct replacement of 7.x-2.x. Then 3.x will include the required changes to the program and scheduling entities to make everything much more user configurable.
