We'll start with a nice bit of Zeppelin.
Bach -- The Well-Tempered Clavier, as recorded by Glenn Gould (great sound engineering job, you can't hear him humming along)
Britney -- I'm an 'older male fan', I'm sure you understand
Barry Martin's Hamsters -- assorted Americana, especially Texas Boogie, strictly a religious matter
Stevie Ray Vaughan -- same again but for the mainliners, come to the source!
Claude Debussy -- Nuages, La Mer, that sort of stuff. And La fille aux cheveux de lin of course.
Chopin preludes, bit of Elgar....
Soundtrack albums are good, especially Blade Runner or Twin Peaks. Terminator 2. A whole stack of John Williams's Star Wars work.
Or, on a fine day, open the QuickTime player, find the M4V of Dino de Laurentiis's 'Waterloo', and leave that running in the background....
Lord Uxbridge: [clears throat] Sir.
Duke of Wellington: [removing his copy of The Times from over his face] Ah, Uxbridge.
Lord Uxbridge: As I am second-in-command and in case anything should happen to you, what are your plans?
Duke of Wellington: Why, to beat the French!
[goes back to sleep, replacing the newspaper]
Lord Uxbridge: By God, Sir. I've lost my leg.
Duke of Wellington: By God, Sir. So you have.
Field Marshal Gebhard von Blucher: Raise high the black flags, my children. No prisoners. No pity. I will shoot any man I see with pity in him.
... not that there's much wrong with Sharpe's Waterloo either. "I wish you joy of the day!"
