Starting September 16th — two years and a day after its birth — Zune users will be able to wirelessly download or stream songs from wireless hot spots.

Microsoft proudly announced the software and firmware updates that let Zune owners discover, tag and purchase songs directly from the player's built-in FM radio.

“We’ve always known that radio is the primary source for discovering new music," remarked John Hogan, president and CEO of Clear Channel Radio.

When a Zune owner hears a song on the radio that s/he likes, the user can immediately tag and download that song, or — if not connected to the internet at that moment — queue it for later purchase.

Users can also wirelessly access the Zune Marketplace store on the go - to which Microsoft recently added hundreds of TV programs to keep up with iTunes' extensive offerings.

Music downloads are "pay per track" or by subscription, which runs at a flat rate of $14.99/month. A subscription grants access to other Zune services, such as programmed channels and personalized "picks," using Zune's recommendation algorithm.

A social music community also introduces new music.

The players used to come only in 4GB, 8GB, and 80GB models, but now include 16GB ($199) and 120GB ($250) capacities, and in new colors: blue-on-silver and all-black.

Meanwhile, yesterday Apple unveiled the fourth-generation iPod Nano and an iPod Shuffle with updated design features.
