Perhaps you found this site because you like lists, but perhaps you have been turned off by the idiosyncratic nature of some of them. Let me therefore recommend an even larger collection of lists from an altogether different Dave. I will call him Other-Dave to avoid confusion and entertain myself. Other-Dave's Music Database's collection of best-of-lists is quite impressive. Most of them appear to be aggregate lists, so there aren't a lot of surprises. I like surprises myself, but I also see the advantage of a list that is generally free of them.
I like the aggregate lists best when all the sources are provided, such as Other-Dave's list of the top 50 progressive rock albums. At the bottom of the post, there are links to all the other lists/sites that fed into the aggregate list. Thus, you get the advantage of the aggregate list plus the serendipity of some of the more adventurous individual lists. Actually, in this case, I didn't think the individual lists were terribly adventurous either, but this timeline list was more interesting than some of the others because it brings prog into the present. You can find more thoughts on prog (from me-myself-and-I-Dave and not Other-Dave) on this previous post.
Other-Dave does have a few posts that are truly his own favorites, such as his top 100 albums. Here, we learn that Other-Dave is a big fan of Marillion and Styx. It's pretty much all commercial (or borderline commercial, e.g. Marillion) fare, but it's also reasonably diverse given that limitation. You don't see a lot of lists, for instance, including both Lynyrd Skynyrd and Crowded House. Kevin GIibert is one artists on the list that shows up multiple times, and I confess I have no familiarity with him. Allmusic.com seems to like Kevin GIlbert's records also.
Maybe one of us (me or Other-Dave) could appear in some future version of These Are the Dave's I Know. Then again, maybe you're looking for neither of us and just planned to have bacon and eggs at Dave's.
