I always hated how anything downloaded from Itunes made it so you couldn’t play the stupid mp4a file on anything but an IPOD.  Seeing as how I purchased a new phone that has a gig of space for mp3’s I needed a converter.  Free Audio Pack to the rescue!  It converts those ridiculous files (as well as many others) to mp3s that I can load onto my phone or burn to an mp3 cd to play in my car.  The price was right too.
