That's the links below for the original uploads. Obviously now your question has been answered as they have been uploaded today with download links. Personal opinion is the download links are not any better sound quality as I don't think they are the original files they must have. They are 128kbps and might be just an MPEG-4 to MP3 conversion?
Undergroundradio which I don't think you have any sets of theirs on here do the same thing from their Mixcloud uploads (convert MPGE-4 to MP3) then put them on 'hearthis.at' but they don't even offer a download option though it is possible. Obviously you can rip them and if you want an MP3 not an MPEG-4 it saves you converting them.
