More music! Across the nation! With Spar Live!– urges the pre-recorded female voice across the shop’s speaker system, in a tone that combines the rapture of corporate employees flattering the boss with the reassuring cheer of a parent telling a timid child about a surprise trip to Disneyland.

How could you stand to buy your baked beans without the accompaniment of golden oldies, new tunes in an oldie style, and lots of smug jingles reminding you where you are, you idiot?Whilst some shoppers might prefer the constant honking of horns by clowns riding up and down the aisles on unicycles, radio remains a much more cost-effective way to really piss people off.
