IFTTT Youtube liked video to Spotify playlist filter

Filter.js

// Removes stuff from YouTube video names to make it easier to find the song on Spotify
// Add this to the filter section of your IFTTT applet after the Youtube Trigger, before Spotify.
// Spotify title in the applet settings can be whatever (so long as it's not empty) this replaces it.

var title = Youtube.newLikedVideo.Title

// Some videos use a dash or colon instead of hyphen.
var titleSplit = title.split('-')
if (titleSplit.length != 2){
  titleSplit = title.split('–')
  if (titleSplit.length != 2){
    titleSplit = title.split(':')
  }
}

if (titleSplit.length == 2) {
  var artistName = titleSplit[0].trim()
  var trackName = titleSplit[1].trim()

  // Remove non-track name stuff
  var trackTerms = ['ft. ', 'ft ', 'feat. ', 'feat ', 'featuring ', '(', '['],
    sl = trackTerms.length
  while (sl--) {
    if (trackName.indexOf(trackTerms[sl])!=-1) {
      var removeIndex = (trackName.indexOf(trackTerms[sl]))
      var removeString = (trackName.slice(removeIndex))
      trackName = trackName.replace(removeString, '')
    }
  }
  
  // Remove subsequent artists
  var artistTerms = ['/',' & ',',',' and '],
      al = artistTerms.length
  while (al--) {
    if (artistName.indexOf(artistTerms[al])!=-1){
      var removeIndex = (artistName.indexOf(artistTerms[al]))
      var removeString = (artistName.slice(removeIndex))
      artistName = artistName.replace(removeString,'')
    }
  }
  trackName = trackName.trim()
  artistName = artistName.trim()
  Spotify.addATrackToAPlaylist.setSearchQuery(trackName)
  Spotify.addATrackToAPlaylist.setArtistName(artistName)

} else {

  Spotify.addATrackToAPlaylist.skip()
}

Modified from this reddit thread.

This one should result in long song names featuring multiple artists or information such as (Official Video) or [HD] etc. to be removed from the Spotify search query.
