Albums got docked points if the artist went on to far greater achievements (which is why Please, Please Me and Greetings from Asbury Park, great as they are, didn't made the top ten); conversely, we gave a little extra recognition to great debut albums that the artist never matched (hello, Is This It and Illmatic!).
That's the part that makes this interesting and difficult to judge -- got me thinking about a more "scene-centric" list. Off the top of my head I got ...
Taking Back Sunday - Tell All Your Friends
Say Anything - Is a Real Boy
The Living End - Self-Titled
