I think the great thing about Pink Floyd's albums is that they can mean different things to different people. People can make their own meanings based on experiences they've had in their lives or just how they interperated it. For instance When I first heard Welcome to the Machine I thought it sounded like a jail, but my dad told me it was about the pressures of the recording industry. I'm 14 too.
