The allure of shuffle mode XXI

Frequently, the guitar is integral in setting a song's tone.  That was evident recently when iTunes shuffle mode played these four songs in a row:

• It Never Gets Easier-Muriel Anderson
• A Crooked Road-Darrell Scott
• Kite-Mascott
• Knife Edge-Brooks Williams

Across those four songs, the guitar conveyed melancholy, resolved, whimsical, and hopeful moods, in that order.  After hearing those tunes, I don't see how a listener couldn't appreciate the instrument's range.
