Its not a problem, or it shouldn't be. People will have different scales no matter what. Let them. They have the freedom to do so. It wouldnt be so confusing or bothersome if you paid more attention to the review than the score.
1. Yeah I was going to include that people should just read the reviews rather than worry about the score, but thought I'd keep it brief.
2. I do still think if a site is going to score records, it should have a standard way of doing it so it is fair to all artists and consistent. Reviews can be different opinions of course but no good one person saying my record sucks and giving it 5/10 then another person saying your record is good not great and giving it a 6/10.
3. I posted that before I realised Jenkins had been having a long argument and, upon reading the prior comments, immediately regretted fuelling any more pointless discussion!
