Alias for downloading youtube music and automatically tag it

ytmp3.zsh

# Nice alias for youtube-dl for downloading mp3 from youtube 
# and other media services, parse the title and the thumbnail
# to add the adequate metadatas.

# You need to provide a youtube id.
# > ytmp3 venrUQLZ87M
# or 
# > ytmp3 https://www.youtube.com/watch?v=venrUQLZ87M
# It works with playlists too !
#
# You can also provide it by a list of ids in a file. Yay!
# > ytmp3 -a mylistoffiles.txt

# first you need to install youtube-dl (https://github.com/rg3/youtube-dl/)
# > brew install youtube-dl
# and ffmpeg
# > brew install ffmepeg
# and add this alias to your .zshrc or .bash_profile
# I harcoded the output directory to ~/Downloads/ but you can revove it if you 
# prefer to download to the current working path.
