If you have no playlists or aren't a paying subscriber, playlistArr in getPlaylists.genSonglists is undefined. A falsey check allows for an empty array to be returned, and the script will continue and export all "Thumbs Up" and "Library" songs.
This issue causes the Export Playlists button to "do nothing", and the fix here should close issue #10.
