originally applied to any organisation/artist "going it alone" without the funding/guidance of a company/record label. now in music can mean bands that have massive record deals like Arctic Monkeys and Frans Ferdinand.

Indie is short for independent, it can basically be applied to any album/artist that was created without the help of a record label.
