Downloading wrong (my) playlists after logging in.

[shrinidhi111]

I was downloading all the playlists from https://www.youtube.com/user/SingingMadeSimple/playlists and everything was working well until it hit upon a age restricted video and stopped. To work around it I decided to provide my login credentials. This is the code I typed with my username :: (password I typed later)

youtube-dl -o "%(uploader)s/%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s" -f 18 -u
shrinidhi111 https://www.youtube.com/user/SingingMadeSimple/playlists

But to my astonishment it's downloading all my playlists instead of what's given. I don't know what's going on.

For the time being I removed my username and added -i tag to ignore the age restricted videos to continue downloading rest of the playlists. Here's part of output ::
