New Download links for iPod-ready AAC versions of mixes (continued) posted by: dj_jcee posted: 04.25.07 continued from previous post... These m4a (AAC) files are designed to be played with iTunes and iPod (any version). For more information Google search "enhanced podcast" and it will tell you all you need to know. Confused? Then stick to the mp3 format for now, but for those of you who are iTunes & iPod savvy, you will love the new Download Link option. Cheers!
