How does Facebook Music Object works?

i'v built a music canvas application and i'm trying to figure out how the Facebook Music and Audio Objects work.

i did everything the Open Graph Music Documentation Page said

here is my open graph meta tags for a song page.

<meta property="og:title" content="artist name - song name" />
<meta property="og:type" content="music.song" />
<meta property="og:image" content="artist image url" />
<meta property="og:url" content="song page url" />
<meta property="og:site_name" content="site name" />
<meta property="og:audio" content="song mp3 url" />
<meta 开发者_如何转开发property="og:audio:type" content="audio/vnd.facebook.bridge" />
<meta property="music:musician" content="artist page url" />
<meta property="music:album" content="song album url" />
<meta property="fb:app_id" content="my app id" />

i'm not getting any erros but..

i debugged the url and this is what i'm getting

• no artist name.
• incorrect song title.
• no album name.
• when i publish the song url on my facebook status i'm not getting any audio player.

note: im getting the correct src i just deleted it from the image.

i'm trying to figure out how to deal with Open Graph beta Music Object for 2 days now.

can someone please help..

thanks in advance.

edit:

if you look at the image i attached there is no artist name, album name and the title of the song is incorrect (facebook took that title from the mp3 filename) when i try adding go:audio:title, 'go:audio:artist, 'go:audio:album it works well but the facebook debugger returns error.

here is the debug information.

Facebook states: "Facebook Open Graph Music is only available to whitelisted partners at this time." Are you whitelisted partner?

og:audio:type should be application/mp3 to play, everything else seems fine to me

Everything looks good. Just make sure that whatever you put in og:url is the actual page with the <meta> tags.

All og:url means is "Completely ignore this page and go over here to find the tags".
