I need a FREE program to automatically change song info and album art.?

[Andy]

I've googled the heck out of the internet but still I can't find a free program to use. I have a mac, I'm looking for something so I don't have to change the info individually per song. Something that searches the internet for the information and the album artwork. The closest thing I found was SongGenie and CoverScout. Both work great but they aren't free and my trial is up. If you know of a mac program that can do what I want feel free to let me know. I'm sure I'm not the only one.
