You are absolutely right. It is just that a certain style of music developed on the independent labels and they tended to be song-orientated, guitar-based, anti-synthesizer, like Oasis.
Huh? But Oasis is not indie though.
I just find it funny when websites like AllMusic refer to bands like Keane and Killers as indie when they are extremely mainstream.
