Amazon Cloud Player Download Bookmarklet

amazon-cloud-player-download.js

// I wrote this bookmarklet because Amazon has ended Linux support for downloading MP3s,
// and now I have to download songs separately through Amazon Cloud Player.
// This bookmarklet helps a bit with this, but it's far from perfect.
// When a list of songs is shown in Amazon Cloud Player, it clicks the song checkbox and
// the download button separately for each song, while waiting a few seconds in between songs.
// I encountered the issue that I cannot download more than a few songs simultaneously;
// the rest will just not show a download window. Not sure whether my browser or the server
// is doing this, but you might want to set the value of songdelayms high enough.

// The script is not really that useful, but it was fun to play around with this.

// bookmarklet version:
javascript:(function(){var%20button=jQuery(".actions%20.download").parent()[0];var%20songs=jQuery(".songTracks%20input.checkbox[itemtype='song']");jQuery(songs).filter(":checked").each(function(index,elem){elem.click();});var%20songidx=0;var%20clickdelayms=200;var%20songdelayms=4000;function%20download(){var%20song=songs[songidx];song.click();setTimeout(function(){button.click();setTimeout(function(){song.click();songidx++;if(songidx<songs.length)download();},songdelayms);},clickdelayms);}setTimeout(download,clickdelayms);})();

// plaintext version:
// get the download button
var button = jQuery(".actions .download").parent()[0];
// get the song checkboxes
var songs = jQuery(".songTracks input.checkbox[itemtype='song']");
// uncheck all songs
jQuery(songs).filter(":checked").each(function(index, elem) { elem.click(); });

// vars for download function
var songidx = 0;
var clickdelayms = 200;
var songdelayms = 4000;

// download a song, wait a bit, then download next song
function download() {
    var song = songs[songidx];
    song.click();
    // wait before clicking, else it fails sometimes
    setTimeout(function() {
        button.click();
        // next download after some ms
        setTimeout(function() {
            song.click();
            songidx++;
            if (songidx < songs.length) download();
        }, songdelayms);
    }, clickdelayms);
}

// start downloading
setTimeout(download, clickdelayms);
