I will speak for myself, I only listen to a radio if its content is 100% the same genre of music, else I would just make a youtube playlist and done.
That's the other thing too, you cant please everyone and Ragezone has a wide range of musical tastes. I doubt that many people will listen to the same thing that mental would listen to and to what I would listen to. I may be pleasantly surprised, however the greater number will vary across country, age and culture.
This could be resolved with a request system.
But the whole radio thing itself wouldn't benefit the forum at all. I wouldn't say that this is a bad idea, it's just not very suitable for a forum.
a podcast would be great.a radio i don't think so
