If there were others interested, it would be great to provide a curated station run by a dj based on the different musical genres.
This is not a new concept for having internet radio stations but I wonder if it fits well in the spotify portfolio with the market saturation, library, application and subscription model. WOXY was a great example of an internet radio station for alternative music years ago before it shut down.
I would suggest that this would only be available to premium members as to have a revenue stream to not rely on advertisements which would mess with the flow of the programming.
Discover Weekly is great and I am sure much work has been put into the algorithms for finding new music but having different people selecting and playing songs based on different focused shows would also be great. Deep cuts from popular artists with minimal plays, new music highlights, top X format. These are all possibilities and would take advantage of the data already being collected across the platform. Clearly a request based format is just what is available now, but there could always be suggestions submitted to the dj's.
