Sienifork is a small spare time project by last.fm users musicishorrible and pellejoku, where they pick random albums, listen to them, and score them according to set standards. The final score given on this RYM user is nothing more than an average of these two scores - to determine whether an album can be considered sieni-approved or not.

Score distribution (from 5 to 1) because statistics are nice:
musicishorrible: 0-1-8-36-11
pellejoku: 0-1-6-46-3
