At this point, I don't think they'll be released. I was excited to see a red response initially, but now all I see is stalling, which I guess means that maybe there's some hope, but I personally don't see it happening. That said, the "reason" that there hasn't been enough time is hard to believe. I just went ahead for kicks and giggles to see how long it would take, as someone who's never used Soundcloud before, to take some lossless music and put it up into a channel (or "set" as I came to discover). Including the time spent registering, confirming my e-mail, converting to FLAC from WAVE, uploading, dealing with the problems I faced where Soundcloud utilizes the filenames instead of tagging, and everything else in between, I finished in just under 10 minutes.
