that’s a good criteria . every song being a classic. Surfer Rosa and Daydream Nation have songs on them that don’t quite do it for me though. There are a lot of album however that have only one song that stop them from being all classics so I would still include them (like Buffalo Tom’s Let Me Come Over). I would also make give a full stars to an album that does everything it set out to do or is a musical turning point like Surfer Rosa, Daydream Nation, or YLAOM.
