I'm a pretty big "albums only, no playlist" purist - even for playlists I listen to, I usually wind up scoping any artists that catch my ear in full.
All that being said, I will *never* listen to Sunbather piecemeal. Every song on it rules, but within the context of the album as a whole, it's an entirely different experience. In general, I think that even really good singles are better when in the context of their album.
