I wanted the output to look like this:

38 Special - The Very Best of the A&M Years (1977-1988) - Rockin' Into the Night
38 Special - The Very Best of the A&M Years (1977-1988) - Hold on Loosely
38 Special - The Very Best of the A&M Years (1977-1988) - Wild-Eyed Southern Boys
38 Special - The Very Best of the A&M Years (1977-1988) - Fantasy Girl
etc...

// Solution - probably a bit crude but it works.
// the foreach loop can go into a function
// Input array is $playlistid (see below)

unset($playlistid[0]);
array_pop($playlistid);

$album = preg_grep('/\bAlbum:\s/', $playlistid);
$artist = preg_grep('/\bArtist:\s/', $playlistid);
$title = preg_grep('/\bTitle:\s/', $playlistid);

$album = array_values($album);
$artist = array_values($artist);
$title = array_values($title);
$arr_count=count($album);
$range = range(0,$arr_count -1);

foreach($range as $list) {
        $artist_title = trim(str_replace("Artist:", "", $artist[$list]));
        $song_title = trim(str_replace("Title:", "", $title[$list]));
        $album_title = trim(str_replace("Album:", "", $album[$list]));
        echo "{$artist_title} - {$album_title} - {$song_title}\n";
