Not only is nothing perfect, but the very concept is evil.
It's one of those ideas - like justice - that cause people no end of greif pursuing.
Some shimmering chimera, always just out of reach.
Something with no basis in reality.
That being said, here is list of albums that I coinsider - at this particular point in time and no other - to be perfect. By perfect I don't mean soul blistering religious experience of enlightenment every time I hear it perfect, I just mean that there aren't any bad songs - nothing I'd be willing to skip. Additional points if the album comes together as some kind of unified whole (props, Peter + Pink). There are, admittedly, a couple of albums that technically do have one not so great track (The Beatles, The Cars, Fountians of Wayne, and Synergy all fall into this category), but have so much overwhelming momentum from the rest of the album that it seems petty to quibble over one slight bump in the road. Oh, and only original releases count, no compilations or greatest hits.
