Easy way to download whole youtube play list and convert them to mp3
I love to keep my favorite musics on youtube. As the time go on some music has been deleted. So I have to download it and keep it local. But keep it as a video file will waste too much storage so I want to convert to mp3 file. After doing research I found a great solution. just one command to make things done. This app will download every youtube video in the list (and yet it can download a single video) then convert each video to mp3 files.
How to install
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install youtube-dl
youtube-dl --extract-audio --audio-format mp3 --ignore-errors <www.youtubeUrl-or-playlistUrl>
