It's hard to rank their discography because 1. there's so many albums 2. by the time you do a discography re-listen and get towards the latter half, a lot of the stuff you listened to way earlier starts to blur a bit. With that said, i'll throw out my current (which will probably change by the time I've posted) but i'll just go on gut feeling and a lot of the lower ones might not be bad, just ones I don't feel a strong urge to revisit compared to the higher up stuff.
