As early as Tuesday (9/11) of this week, I was able to upload MP-4's to Soundcloud, which would accept the audio only. On Wednesday (9/12) this capability disappeared, and I now have to re-render my MP4 files to MP3 to get Soundcloud to accept. I get it that Soundcloud officially accepts only MP2 and MP# files...but I'm telling you I WAS able to upload MP4's as well...until Tuesday. Anyone have any idea what changed??
