Having just listened to Rodney Crowell’s The Houston Kid, I could nominate any number of songs on this fantastic album. I’ll say "Why Don't We Talk About It", a song Tom Petty wished he could write. The chord progression, the melody and harmonies, the musicianship, all stellar. The song even has a bridge/middle-8, the writing of which is a sadly-dying art.
Also on the album is a new song Rodney and his once-Father-In-Law Johnny Cash (Crowell was married to Rosanne Cash) collaborate on, the very cool "I Walk The Line (Revisited)".
