PHP MusicBrainz get the first release date - php

Question

i am trying to get the first release date of a song using Musicbrainz. To get this i am using the mikealmond musicBrainz library.
The problem i have is that when i try to execute exactly the same code as in this example (https://github.com/mikealmond/MusicBrainz/blob/master/examples/first-recording-search.php) i always get an authentication error.
Client error response [status code] 401 [reason phrase] Unauthorized [url] http://musicbrainz.org/ws/2/artist/0383dadf-2a4e-4d10-a46a-e9e041da8eb3?inc=releases+recordings+release-groups+user-ratings&fmt=json
Therefore i tried to add my username and password to the request:
$brainz = new MusicBrainz(new GuzzleHttpAdapter(new Client()),'myusername','mypassword');
$brainz->setUserAgent('myapplicationname', '0.2', 'http://localhost:443/');
If i call the url in the error message manually and enter my username and password i get the array i expect.
I just had a discovery: If I removed -"+ user - ratings"- it does not require authentication.
Therefore i commented the lines with "user - ratings" in my project
Now i think it works, but the performance of the query is very bad and often i get Error 503 // The MusicBrainz web server is currently busy. Please try again later. //
It takes a few seconds just for one song. Does someone know if this is normal or if i still have some kind of mistake?
My code....
//Create new MusicBrainz object
$brainz = new MusicBrainz(new GuzzleHttpAdapter(new Client()), 'username', 'password');
$brainz->setUserAgent('applicationname', '0.2', 'http://localhost:443/');
// set defaults
$artistId = null;
$songId = null;
$lastScore = null;
$firstRecording = array(
'releaseDate' => new DateTime()
);
// Set the search arguments to pass into the RecordingFilter
$args = array(
"recording" => 'we will rock you',
"artist" => 'Queen',
);
try {
// Find all the recordings that match the search and loop through them
$recordings = $brainz->search(new RecordingFilter($args));
$recorings i can print and in the loop i can print each $recording, but the error comes when i extract the informations
/** #var $recording \MusicBrainz\Recording */
foreach ($recordings as $recording) {
// if the recording has a lower score than the previous recording, stop the loop.
// This is because scores less than 100 usually don't match the search well
if (null != $lastScore && $recording->getScore() < $lastScore) {
break;
}
$lastScore = $recording->getScore();
$releaseDates = $recording->getReleaseDates();
$oldestReleaseKey = key($releaseDates);
if (strtoupper($recording->getArtist()->getName()) == strtoupper($args['artist'])
&& $releaseDates[$oldestReleaseKey] < $firstRecording['releaseDate']
) {
$firstRecording = array(
'releaseDate' => $recording->releases[$oldestReleaseKey]->getReleaseDate()
);
}
}
pr($firstRecording);
} catch (Exception $e) {
pr($e->getMessage());
}

$brainz = new MusicBrainz(new GuzzleHttpAdapter(new Client()), 'username', 'password');
You must set your MusicBrainz account credentials. Replace 'username' with your account username, and 'password' with the password used to login to MusicBrainz.org
