All Facebook has uncovered a recent update on Facebook that see’s the social networking behemoth allow its users to post MP3 files onto their profile pages, just as you would with a URL.
As far as I can tell, you still aren’t able to upload audio files to Facebook without using some third party app. But to get a music file to play on your profile just post a link to a file that ends with .mp3.
As All Facebook points out, majority of original MP3 music files aren’t easily found for your standard Internet user. Music is usually deeply integrated with a site’s music player and so you can’t link to the MP3 file itself. Fortunately there are a heap of file sharing services out there that will let you upload an mp3 file you want to share. You can then link directly to that file on Facebook from your profile page, I just did this myself and took no more than 2 minutes.
Anytime you link to an MP3 you can enter the song title, artist, and album, and it will be playable from within the feed.
I must say though, I am looking forward to being able to share (and embed) music directly from Spotify. Don’t have access yet? You’ll love it when you do. Trust me.
