Thinking about it, it would be near impossible to make any music listener happy with any "best of" or "top 20, 50, 100," but to be a little more fair and/or more accurate, one would almost have to break down the musicians by genre. Of course, some played any style you want, but this came from RS Magazine which if I remember correctly was about Pop & Rock music. Look at the Rock & Roll hall of Pretty Good over in Cleve Land. There are people/groups in there that don't even fit in the R&R category.
As far as Neil Young goes, the only reason I would ever own any of his albums would be to get people to leave my house when they stay too long. Definitely one of the best buzz-killers of all time! I do believe if one doesn't make it to Heaven, there's a room down below with the best surround sound system ever made and there's a continuous loop tape of him singing & playing, with Yoko Ono singing (or squeaking) backup.
