This assignment is one I would give my general music students when I had them listen to a specific song. I always played the song twice, once for listening and once for writing on the assignment. I used it as an opportunity to practice critical listening skills for instruments, as well as a way to expose them to different genres of music. I made sure not to always play "the boring stuff". Sometimes I would ask them to compare and contrast songs, such as "Eye of the Tiger" and "Roar" by Katy Perry, or two versions of the same song but sung by different artists. I found it was always hard for my students to reflect on what they thought about the song, which is why I pushed them to do it. As I said, sometimes I gave them specific compare/contrast prompts. I found the assignment to take about 15-20 minutes. I hope you find it useful.
