Rateyourmusic is the best music database website on the net.

So many bad ratings for good albums (i really can't understand some RYM raters)

If I really can't stand them (or more true wrong genre) I don't rate them. See no reason too give Styx or every released rap-artist no better than one star.

5.0 - Masterpiece - Awesome
4.5 - Brilliant
4.0 - Great - worthy of recommendation
3.5 - Very Good
3.0 - Good/Decent
2.5 - Average - sometimes harmless
2.0 - Disappointing - passable
1.5 - Bad
1.0 - Terrible - bro in the band would't help
0.5 - Unlistenable
