These lists are really nothing to get excited about. Every person alive would come up with a different list of the 500 best.
If you are expecting a lot of post bop jazz to show up in a Rolling Stone 500 best, I'm not sure what you're thinking. Your time would be better spent reading DownBeat. Can you imagine Bob Dylan or the Stones showing up in a DownBeat best of? By chance, there's a Critic's Poll on DownBeat right now.
Check out the list, if there's something there that you like, read the review. If not, put it back in the rack and go home and listen to that death metal band you like so much and congratulate yourself on your good taste.
There is always Amazon for people who wish to be amateur reviewers. You can review individual albums and you can make up your own best of lists, and they'll be published on the web for the whole world to see. Don't get mad, have a go at it yourself.
