What is it?

spotify-metadata is a Ruby gem that provides easy acces to the Spotify Metadata API. The API has serves two functions: searching for metadata – artist names and their Spotify URIs, the tracks in an album, the artist(s) of a track, etc – and looking up Spotify URLs.

Usage

Here are some little, (mostly) useless examples for you to see how this gem works.

require 'spotify'

# Searching
artists = Spotify::search_artist 'Radiohead'
puts artists.first.name # => "Radiohead"

album = Spotify::search_album('The King of Limbs').first # notice .first.
puts "#{album.artist.name} - #{album.name}" # => "Radiohead - Kid A"

# Looking up Spotify URIs
artist = Spotify::lookup_artist 'spotify:artist:1Z2KInfSmPOzAIYyiaXeti', :album
puts artist.name # => "Youth Lagoon"

artist.albums.join ', ' # => "The Year of Hibernation, The Year of Hibernation" (See the 'Known Bugs')

album = Spotify::lookup_album 'spotify:album:4oGbmR7dENuqtRyvX8MShq', :track
album.tracks.each do |track|
	track.name
end

Installation

Just type gem install spotify-metadata on the command line. Or when using Bundler:

gem 'spotify-metadata', :require => 'spotify', :git => 'git://github.com/britishtea/spotify.git'

Known Bugs

• Track numbers, artist IDs and external IDs can't be looked up (the API uses track-number). Use something like Spotify::Track.send(:'track-number') to work around this problem.
• When requesting the albums by an artist (Spotify::lookup_artist url, :album), the same album is sometimes listed more than once. This is due to Spotify providing different editions in different territories. Something like artist.availability['territories'] can be used to filter out the relevant edition.
