Update (Sept 7th, 2012):
The instructions in this post are no longer valid. However, I am leaving this post as it contains some useful information and comments.
Facebook tools/apis have been constantly changing. If you want to use their tools going to their website directly is your best bet.
If you maintain a Facebook page for your band, Facebook provides an application called the
Music Player that you can use to upload songs to your band’s page.
When you upload a new song it is automatically published into the news feed of all your fans. You don’t have to send out fan updates to publicize new songs. Publishing into your fan’s news feed is currently the best way to get the attention of Facebook users.
Here are the steps to add
Music Player to your Facebook band page :
Login to Facebook. Make sure you are the page admin for the page you are editing.
Click on “Ads and Pages” on the left menu.
Update: If you don’t see the “Ads and Pages” link on the left menu simply go to this link to edit pages http://www.facebook.com/pages/manage.
Click on “Edit Page” link at the bottom of the page you want to edit.
Click on “Browse More” which will take you to the application search page.
Type music player in the search box and hit enter. This should take you to the Search Results page.
You should be able to see the “Music Player by Facebook” application in the search results.
Click on it.
Click on Add to my page. This should pop-up a dialog. Select the page.
You should now be able see the “Music Player” application on your page.
You can edit the “Music Player” application to upload and display albums on your fan page.
Tip: You can add the “Music Player” to any page in general, not just a Band page.
