Yes, I should have said "Show me all events near San Francisco", because as you aptly point out a single venue is easy to search. The problem is that I have to find all the venues, do all the searches, and then do it again as they add more shows!
So yeah, a single site, maybe one where I can upload my iTunes song list or link to my Pandora or something so it can sort by why I like, would be awesome.

Are you looking for a "show me all shows in San Francisco"? I haven't found a good solution to that either, and things like Eventful, Pollstar aren't the greatest as they simply show too much.
