3 years ago I created a mini-documentary / educational piece on the psychedelic movement for an audio class I was taking at university. The piece was removed by Soundcloud for violating copyright, as I used a snipped from "Tomorrow Never Knows" by the Beatles as an example. I originally thought it might fall under fair use on the grounds of education and commentary, but that isn't really my concern. I would simply like to be able to hear it again, or download it for my own personal collection. I spent a lot of time interviewing, researching, and editing it, but I lost my copy somewhere along the way. Is there any way to retrieve a track once its been taken down for copyright? I'd really like to hear it again.
