Ever wonder how people get the song they are currently listening to to show up on their blog? Well, chances are they are using one of these iTunes plug-ins.
1. Now Playing (Windows)
2. Now Playing (Mac)
3. Kung-Tunes (Mac)
I think that all of the plug-ins work, however, I think that the order I have them in is the order of best to worst (I am just guessing because I haven't tested any of them)
These plug-ins upload a file to a server that contains the current song/artist/etc. I would use one of these plug-ins, but since I'm using Blogger's servers I can't ftp the file to the server. If you are hosting your blog somewhere that lets you use ftp these plug-ins should work for you.
Hope this helps
