// A little bit of Javascript to let you export your Google Music library, playlists, and album track lists :)
//
// I posted this as an answer here: http://webapps.stackexchange.com/questions/50311/print-playlist-from-google-play-music
//
// 1. Go to: https://play.google.com/music/listen#/all (or your playlist)
//
// 2. Open a developer console (F12 for Chrome). Paste
// code below into the console.
//
// 3. All scraped songs are stored in the `allsongs` object
// and a text version of the list is copied to the clipboard. I recommend running
// `songsToText("all",true)` afterwards to get the full CSV information.
//
// 4. If you would like the output in a text format, can call
// the songsToText() function. You can select a style, choose
// the format, and if only liked/thumbed up songs should be exported.
// The resulting list will then be pasted into the clipboard.
// Styles are ` all`, `artist`, `artistalbum`, `artistsong`,
// `artistalbumsong`.
// CSV will result in a CSV file and can be left out (defaults to false).
// Likedonly can be left out (defaults to
// false) or set to true, and will filter all songs with
// ratings greater or equal to 5.
// E.g:
// - `songsToText("all",true,false)` will export all songs in csv format.
// - `songsToText("all",true,true)` will export only liked songs in csv format.
// - `songsToText("artistsong",false,false)` will export all songs as text.
//
// 5. You can then paste the data anywhere you like, for
// example http://www.ivyishere.org/ if you want to add the
// songs or albums to your Spotify account. To make Ivy
// recognize full albums, use the "artistalbum" style. For
// songs, use the "artistsong" style.
// see my answer here for questions: http://webapps.stackexchange.com/a/73792/77056
