Unlike some other social networking sites like MySpace, Facebook does not have an automatic setup that allows you to post music to your profile. But with the advent of a number of outside apps, you can add special features to your Facebook site. The "iLike" music application allows you to post songs to your profile and post information about the music you enjoy.
Log in to your Facebook account and navigate to the "iLike" page of Facebook.
Click "Go to App" at the top of the iLike page. Allow your computer to load the app to your Facebook profile by clicking on the permission box that reads "Allow this application to access my basic information." This will continue the application loading process.
Click "My Music" once the app is loaded. Scroll down to the "My Songs iLike" section to search for songs that you want to add to your profile. Type in the name of an artist or song. If it's part of the iLike platform, the song or artist should appear as a thumbnail image. Once you've found the song or artist you're looking for, click "iLike" to add it to your Facebook profile.
