I actually built another site around most of those ideas you just mentioned (but changed the idea to films, as I found they worked better): http://filmvsfilm.com/ http://filmvsfilm.com/ It's basically all user-generated-content, and it actually does rank on Google for a few things, but it's the wrong kind of traffic: People aren't in buying mode, very few visitors actually click through to Amazon and buy something.
