Get them to pay attention...they're not gonna pay attention to you just because your saying you've done x amount of shows, n' you appeal to _____ kind of people. Get people to call in for your shit...not just one or two friends, I MEAN A LOT of people. Pester them outside the building with people chanting they wantyour song etc. But there's barely any point of getting played on the radio in itself because of the time you'll probably get played...your better off trying to get oppurtunities to perform, handing out your tapes to dj's etc. Then maybe when you built somewhat of a name try n get on the radio.
