+ * @brief Main Driver for the Week 6 "Background Music" Lab. This program uses
+ *  a similar menu style to the previous lab. The user is given a new option to
+ * play 3 different hard coded songs in arrays of "Note" structs, provided by 
+ * the piezoSpeaker.h file. However, the user can now select whether or not the
+ * music should play in the background to allow other functionality. 
+ * Experience: This lab was a challenge for me. I found that understanding 
+ * interrupts, and mainly how to configure them, was a roadblock that took me 
+ * awhile to figure out. Cleary, as this lab is incomplete I was not able to 
+ * fully implement my design. I do have a general idea of the structure of the
+ * program I would like to implement. For my own sake and sanity, I am going to 
+ * work on trying finish this lab at the very least over break just so I can
+ * see what it is like to get an interrupt driven program working. In this 
+ * case I just managed my time wrong and let myself get behind on labs.
