The trope defined under the name Homage doesn't actually describe the usual usage of the word in conversation, although it does describe a variety of homage. That makes it the wrong trope to use for something like what you added a couple days ago to Don McLean's page. As for the right trope ... um. I don't think we have one for the more common usage of "homage".

Uh... Good point. Maybe the right Trope is Shout Out?
<nod> I was thinking much the same thing when writing that. Maybe not "right", per se, but certainly much closer.
