Songwriting:  In this episode Joe analyzes the song "Bad Habits" by Ed Sheeran, Johnny McDaid and Fred Gibson. This composition is a masterpiece of modern song construction.  The techniques employed offer composers, in all genres of music, a model to emulate in their works. The use of repetition and repetition with variation of melody, harmony and rhythm is textbook, along with the use of overlapping section and shifting tonal colors.
