A little bit of everything

I'm sitting in the Hosmer library struggling to estimate the operational costs for electrical energy (i.e., the bill from XCel) for the ventilation system I apparently screwed up in hte last homework. I have the little study room, so my computer has music playing without needing earphones. (nice)
iTunes is set to random tune selection. There are times when it really hits home how diverse one's musical tastes can be. It just pulled up:

Peggy Lee
Rocky Horror Picture Show
Carl Orf's Carmina Burana
Ralph von Williams
Cowboy Junkies
Ladysmith Black Mambazo
Enigma
Leonard Cohen
