Download a list of songs by name

download-songs-by-name.rb

# Requires spotdl and youtube-dl to installed with python3

# Should be a list of search query text for spotify (e.g. `Song Name Artist Name`)
SONG_LIST_FILE = '/Users/Dylan/Desktop/songs.txt'.freeze
OUTPUT_FOLDER = '/Users/Dylan/Desktop/songs'.freeze

File.foreach(SONG_LIST_FILE) do |line|

    'spotdl',
    '--song',
    line.delete("\n"),
    '--output-ext',

NOTE: you have to be on the lookout for warnings like

ERROR: <SONG_NAME> was not found.

in which case manually search for <SONG_NAME> on youtube and download it using

youtube-dl --extract-audio --embed-thumbnail --audio-format m4a '<URL>'

---

There is another warning

INFO: Track not found on Spotify, falling back on YouTube metadata

which means the song will still probably get downloaded from youtube but the downloaded track won't have the spotify metadata attached to it
