Despite the fact that the project can include radio on the app without much hussle, I still feel it may not be in their best interest. Local radio tends to give users a substitute for the streaming app and including the radio to the app may encourage users to use the radio why forfeiting the major reasons for having the app which is for the music streaming.
Its not only having radio but streaming music channels should also work well. Depends on what is there in the roadmap?
Music tv streaming is hard. every country might have their own music channels. That too not just one but could be atleast 10s to 100s depends on the country size.
