Youtube-dl download Commands

The trick here is in the URL. It is not just cut and paste you need to remove the v=493942 (or whatever) and just leave the list=(value). of course you would need to start with a playlist URL to begin with:

 youtube-dl -cit --playlist-items 2-41 https://www.youtube.com/watch?list=PLH0Szn1yYNeeVFodkI9J_WEATHQCwRZ0u 

Windows:

youtube-dl -f bestvideo+bestaudio link

get playlist audio:

youtube-dl -cit -f 140 --playlist-items 1-24 https://www.youtube.com/watch?list="whatever list id"

youtube-dl -f 137+bestaudio --merge-output-format mp4 "youtube link"
