Search the library, make requests, find out who sang that song, who wrote that song.
Since starting the show in 2000, I've collected almost every bluegrass (or near-bluegrass) release that I can get my hands on. Certainly all the ones released from record labels and major bands in the USA. In this part of the web site you can search the library, keep track of what gets played on air by looking at the playlists, and see what is getting most airplay in the last 100 shows in the section called "The Dawg's Hot 100"
