I took Music Industry 105 with Professor Leaf and his class was without a doubt the most entertaining class I've ever taken at UCLA. Class was held once a week, 2.5 hours long with special guests from the music world. Exams were also fun but also mind provoking and as long as you attend class, you won't have a single problem.
Winter 2021 - Professor Leaf is really awesome! It's clear that he cares a lot about his students and the class content. You are expected to watch several music documentaries each week which can kind of become a drag, but the accompanying written assignments are super easy as long as you paid attention to the films. Grading in this class is lenient, so as long as you answer the homework questions thoroughly, you should do very well. There are no tests in this class, just a major report and a final project. Overall, I would highly recommend taking this class. Just be sure to spread watching the documentaries out each week (unless binge-watching is your thing). Is the workload somewhat tedious? Yes. But is it easy and interesting? Also yes.
Summer 2017 - Highly recommend this class! You watch interviews between the professor and famous songwriters and write your thoughts on them. The class is a lot of busy work, but worth it and the professor really cares. As long as you turn in all of the assignments, you will do really well in the course!
