They might have a few of those singer/songwriters listening, but unless a stations programming philosophy/formula/format is built on music discovery, most people wanna hear whats familiar with a few oh wows here and there.
If I play a crappy song or two here, I'll hear about it. In a place like the Nashville area, they'd probably just find another station and not come back.
If some indy music fits the sound of the station, play one every once in awhile. But also.. if you start playing them, expect to get a ton of submission once word gets out. and then be ready to be inundated with people submitting their stuff then getting back to you when you dont reply to them.
If this is meant to be a real life/real world expierience in radio, then it sounds like WVCP is doing it right.
Would a speciality show, say on a sunday night of local/regional/state artists be a bad idea? Maybe not.
We're radio people, we think about and listen to.. the radio differently than everyone else
