This thread is most helpful.

Also, there are many others on Mudcat. If you put "radio" in the filter, and set the date to "all" you'll see a long list, many of which can be helpful.

Then, go to FOLK DJ and read through their posts. They are a wealth of info on what stations/shows are currently active - and who is playing what sort of music.

And remember; asking "how do I select radio stations to send my music?" is a bit like asking, "how does mathematics work?" We can give you some answers, but until you roll up your sleeves and practice it in your own world - you won;t get anything out of it.

Consider this ansewr (and others) a Mathematics text book.

... all the best!
