SoundCloud just made what could be one of its most detrimental mistakes ever.

Thanks to a coding error during routine maintenance, the streaming service accidentally made some private tracks public between 12:54pm and 5:12pm UTC time on Tuesday, September 6th.

They’ve tried to fix their mistake by resetting secret links for all affected tracks, but it’s possible that many artists now have private music floating around. This also means that artists who willingly have private tracks shared (with industry executives, etc.) will now have to reshare all links. OWSLA vocalist Mark Johns was one of the first to share the situation with the public.

So far, no leaks have surfaced, but if they do, SoundCloud could be in some really deep shit.
