I think that the "Pumped Up Kicks" blog post helped me understand the rhetorical situation the most.   "Pumped Up Kicks" had a very upbeat tempo, but when you read through the lyrics it was completely different. In trying to analyze this song you had to answer many questions.  You had to figure out what was possibly going on and why. You had to figure out why Foster wrote this song the way he did and really the rhetorical situation is trying to figure out the answer to a bunch of questions.  These questions range from what the author thinks and why, if it is effective, who is the intended audience for the song, and whether the author gets his point across.  I think that this post alone made me use pretty much the whole rhetorical situation to correctly figure out the analysis of song and the lyrics.
