I work in a charity bookshop, and often get to pick the music we play. I have often played Palestrina (I find Handel too tub-thumping on the whole) and sometimes used the music to get rid of unwelcome customers (like cranking up King Oliver to 11 to make it impossible for a customer to use us as a phone booth with her mobile).

I really wanted to use this one this year:

Douglas Leedy: A Very Merry Electric Christmas to You

but I couldn't find anywhere to buy it. Supposed to be on iTunes but I couldn't find it.
