Though Microsoft left their new Zune hardware relatively untouched, the firmware and corresponding software got a few nice upgrades that add a bit of functionality. In the firmware, Marketplace is now available over Wi-Fi, while FM Tagging lets you mark songs you hear on the FM Tuner, and have them added to your Marketplace cart automatically. On the software side, Picks compiles a list of songs for purchase in the Marketplace based on recent listening habits, Channels offer what amount to preselected podcasts based on your tastes, Zune DJs or selected partners. Meanwhile Mixview lets you visually explore new music by seeing an artist/album's related works, influences and top listeners. Of these new features, the Wi-Fi Marketplace is a solid, necessary addition, and Mixview is a few tweaks away from being downright awesome.
