I'm watching it now because it's been released. I think it's a mistake on Class 101 -- it's a music lecture, but it's a background music. I keep playing the example with Abletone such as code, drum base, etc., but it overlaps with the background sound, and the rhythm is confusing, and it's ridiculous. It's a music class. Does it make sense that the speaker's music examples aren't working... Please upload it again without background music...
