Who are the singer-songwriters heard on the broadcast that Dian Easby disparages so?

Cyril Tawney, Arlo Guthrie, Tom Russell, Bob Ryskiewicz, Jesse Winchester, Gretchen Peters and Leonard Cohen.

Other artists not doing their own songs were Jennifer Warnes (an Ian Tyson song), Johnny Cash (a Tom Russell song), The Bluegrass Gospel Project (a Jesse Winchester song) and Swift Years (an instrumental).

Almost every track, including the four by Ron Hynes, was A-list in my book.
