Microsoft’s latest effort in digital music market is finally paying off. Guess what? On Monday, Zune media player was tramked as the No. 1 bestseller in Amazon’s list of top-selling MP3 players.

Zune, the 30 GB version is priced at $134 and it has outsold Apple’s 4GB iPod nano. On the third place came Apple's 80-gigabyte iPod Classic.

Launched one year ago in November Zune has a a 30GB hard drive, 3-inch QVGA LCD screen (320 x 240), Wi-Fi ‘Zune-to-Zune’ connectivity, FM radio, and access to Zune Marketplace.

Also Associated Press reported that the 80GB  Zune media player launched Tuesday has sold out across the Web.

Announced the new Zune 80GB offers a much larger screen, Wi-Fi syncing with your PC, and a rear panel that can be customized with some cool artwork.

It seems like Zune 2, as it is called by tech and gadgets fans, is not available on Amazon  

While Web retailers have 4 GB and 8 GB versions of the second-generation Zunes in stock, the 80 GB music player is not available on Amazon, Best Buy or Circuit City's Web sites. In June this year, the company said it has sold over 1 million Zunes since its official launch.

Maybe Microsoft is finally catching up with Apple? Let’s wait and see!
