I am on the folk d j list.
Many of the dj's on there (myself included)
post their play list each time they have a show.
There is some specific info about airplay
on their home page http://www.folkradio.org/
If a musician offers their music there, d.j.'s
can contact you if the are interested. The spine
label does help i.d. a recording, and prevents it
from getting lost in the stacks. "green" packaging
is appreciated, as well.

I get a lot of material for my radio show from
contacts I have made there. I have been posting
my play list there for years, and also recently
on my my space page.

Wasn't there a thread about similar topic recently?
(radio wants a song I have not recorded....)
perhaps that was your thread...in any case, good
luck !! I always have loved your songs, and your
creative spirit! how goes it with nursing, by the way?
