I've been trying to upload the "hypothalamus now!" vid from the penal colony "unfinished business" album all doggone day. After trying and failing several times, turns out uploading video with 48k audio is a bad idea. YouTube's encoder does something crazy with the time and doubles it. Since they only allow 5 minute videos, a 7 minute video turns into 14 minutes, and it rejects it. After trolling some forums, looks like converting the audio to 44.1k fixes the problem. We'll see.
