What are they watching?

As my students have turned in another paper, and as I have finally finished grading that paper and have some time to kill during the final exam, I herein present to you the list of full-length films/musicals/operas/video games from which they have each selected one specific song, also listed below, as their objects of analysis. Note that not all of these topics actually fit that rubric; that was merely the assignment, not what they actually turned in. How boring to read papers that actually answer the question!

MUSICALS
Chicago, "We Both Reached for the Gun"
A Chorus Line, "Montage" (all the performances on YouTube are awful; you choose)
Grease, "There Are Worse Things I Could Do"
Gypsy, pretty much all of the songs, but more "Rose's Turn" than anything else
Hercules, "I Won't Say I'm In Love"
High School Musical, "Get'cha Head in the Game"
Phantom of the Opera, "The Point of No Return" and "All I Ask of You"
