I found a nice post about a quick way of converting the AAC files to an MP3 in iTunes. It is the 5th post by jameskhog.

So now that you have a duplicate MP3 in iTunes you can right click on that song and select "show in windows explorer." Copy that file onto a flash drive and then the PS3 will be able to read the song and artist info and display the cover art. Don't forget to change back the importing songs from cd's to AAC lossless rather than MP3 or else you will be importing songs at a terrible quality.
