I think it's a safe bet to say that the most popular kind of song in the Great American Songbook is the love song. "Love For Sale," "Easy To Love," "Our Love Is Here To Stay"—cupid seemed to be behind the creation of most of these songs.
A salute old L-O-V-E this hour, with songs sung by Billie Holiday, Chet Baker, Kurt Elling, Frank Sinatra, Dinah Washington, and many more.
