Collection completed! Thank you @Kells77! For those that are into the terminal I use an open source download manager which provides me a m4a directly from mixcloud.com upon the sets upload. It is known as YouTube-DL and is fairly straightforward.
EDIT: As the Bunkers require a subscription you must pass through the cookies (as I chose to do) in order to verify eligibility to stream/download the mix. Free sets on their page simply require a link inserted to the syntax.
