Use ShareMusic to share on Facebook the music you are currently listening to on your Mac.

It’s easy as 1, 2, 3.

1. Open ShareMusic
2. Add a personal message (optional)
3. Press the Share button

It also lets you control your music playback right within the app and change the message format.

It will share these information on your wall:

• Song title
• Album
• Artist
• Artwork and link to the iTunes Store

Note and disclaimer:

You need to be logged in a Facebook account. Artwork and link to the iTunes Store might not represent the current playing song if the album/artist information is not found.

And iTunes must be running.
