On my bus journey back from London I was - for some reason - considering this, and decided on the following:
* Princess Leia would listen to chart indie and i suspect she would go to student nights, drink alcopops and be the first one to get her "girlies" up to dance when The Kooks came on.
* Darth Maul i suspect would listen to brutal metal. His collection would contain old Dimmu Borgir, Burzum and Carcass.
* Jar Jar Binks would listen to Whitney Houston, cos he's a pussy
So, there are a plentiful number of characters throughout the six films; what do you think they'd have in their collections?
