This AppleScript workflow detects if a song is being played on Apple Music or Spotify, then extracts the names of both the artist and the song, composes a string using a template and copies it to your clipboard.

This is the template used to compose the final string. The URL will only appear if the song is played on Spotify.

♬ <SONG_NAME> - <ARTIST_NAME> [URL] #Spotify|AppleMusic #NowPlaying

 ♬ Woman - Wolfmother  #AppleMusic #NowPlaying

♬ Royals - Lorde http://open.spotify.com/track/4zztp85oS36ijgAWwyhX8p #Spotify #NowPlaying
