It works terribly for responses to blog posts, so as someone who doesn't use it already and whose first exposure to it is this Heroku issue, now I think "Rap Genius works terribly".

... success?

I think UX success is not measured in how many people you've already inflicted a bad design on, but instead by how many you avoid hurting in the first place.

Why not make the rap explanations look different than a style lots of sites use for regular links? (perhaps a big square around the section or something similar)

There are green badges next to their added comments. And a big bold part at the top that says "Click the green links below to see our responses", but I'm not sure it was there before or after they saw these reactions.

edit: I agree with you on the UX part. Just wanted to point out that there was some context clues.

A system appropriate for annotating music is not necessarily appropriate for blogging. In this case, Rap Genius is a horrifically bad blogging platform.
