Question

This issue indicates what I am trying to do should be possible.

I attempted to download via my Go+ account a track I own the rights to from Soundcloud. I'd rather not reveal that track, so here is another Go+ track which I can successfully play in my browser, but cannot download with yt-dlc using my cookie credentials.

Steps to reproduce:

1. Have a Go+ account & be logged in
2. use cookies.txt chrome extension to download a soundcloud.com_cookies.txt file
3. Run the command below

% youtube-dlc -f bestaudio -x --audio-quality 0 "https://soundcloud.com/soundgarden/loud-love" -o "%(title)s.%(ext)s" --cookies ./soundcloud.com_cookies.txt --ap-username "xxxxx@xxxxxx.com" --ap-password "xxxxxxxxxxxxx" -v

Attempting this same command a) without the username password, just the cookies, or b) with just username password, and no cookies file both fail.

Version / format information

What could be going wrong?

Since youtube-dlc is no longer being updated, I would suggest using yt-dlp instead.

Also, the music clip on the link you provided is probably one of the most grating sounds I've ever heard. :-)
