The allure of shuffle mode XC

Today, iTunes shuffle mode strung these three songs from my library together:

• Day's End-Jim Chappell
• Jesu, Joy Of Man's Desiring-Herb Alpert & The Tijuana Brass
• Festival Waltz-Al Petteway

All three songs work equally well as station sign-offs, as each one has a "day is done, and what a positive day it was" vibe.  Who doesn't want to leave listeners with that feeling before the next broadcast day?
