This is the command I'm using: youtube-dl -v -f bestaudio --external-downloader aria2c -o "C:\Users\biscoito\Desktop\otographic\%(uploader)s/%(title)s.%(ext)s" --add-metadata --cookies "C:\Users\biscoito\Desktop\otographic\cookies.txt" --audio-format mp3 --audio-quality 0 https://www.mixcloud.com/otographic/

Update: Was able to run, with the -i flag, I figured out that it's a geolocation block, and should be ignored by default by youtube-dl.
