How would closing all "lookup / reference" questions be an improvement over what we already have (votes, comments)? That's a very important aspect of the suggestion that you are missing.
I don't think eliminating flexibility is an improvement and this situation is too dynamic and subjective. We can already speak through the votes and comments if we have an issue with a specific question. Why do you want to make it a blanket reason to close? I see it generating more problems (and bigger) than the one that you are trying to solve.
I've always had a problem with your argument (which commonly brought), because of all the implications. You are assuming that every outside source is complete, correct, and can't be expanded and/or improved upon. Through all the SE sites there are countless examples of answers that have improved and expanded over something that already was available.
The example you present is overly simple, but that won't be the case for all "reference / lookup" questions. Even your simple example can have unexpected ramifications, like B sides, uncredited songs, perhaps some cover or remix. How do you consistently correctly judge when "there's no reason to believe it's incorrect or incomplete"?
By closing everything "reference / lookup" you are also closing the opportunity for others to show you that the question is not as simple as you thought by building a great quality answer.
I understand where you are coming from, some "lazy" questions lack potential of adding something to the site, but that won't be the case every single time. That's why we need flexibility. In my answers that fall in my area of expertise I have consistently improved upon whatever was available (check here and music SE), and many other users do the same on a daily basis.
So, even if we assume everything is always correct, complete, and will suit every possible asker (a different answer can be carved for different askers, depending on the context), we would also need to assume that every user has enough experience on the subject to correctly and consistently judge the direction the question can follow.
Also, how can we objectively enforce this? Are all reference / lookup questions illegal in your eyes? If not, how and where do you draw a line? If so, we would end up closing most of the questions in this site, and with a similar criteria other SE sites would end up closing most of their questions.
