How does one after they have a song together, how do they go from recording it, to getting it played on the radio?
Radio Play seems to require a record label. So maybe try starting out on Purevolume, Myspace, or sell it on TuneCore, the ppl that get your music on iTunes. generally do w/e possible to get your band/song out there.
a lot of bigger radio stations (like those owned by clear channel) have blocks of time for local music. try submitting it to that show.

somehow i can't help but think this belongs in bandleading
