Review: Nokia Lumia 900 for AT&T
The heart of the 900's media experience is Microsoft's Zune software. The music and video apps are one-in-the-same, as is the Zune content store, which also ties into the Windows Marketplace for Mobile. They are all accessed from the same spot. It also supports podcasts and internet radio services.
One cool thing that Windows Phone now does is recognize all the related applications and pile them into one spot. You may have downloaded Slacker, Vevo, and Rhapsody on your own, but you'll see all of them in the Zune music and video hub.
The Zune content store is a fine place to shop for music and videos, though I prefer to sideload my own (which I have to do with the Windows Phone Connector for Mac application). My favorite feature of the media player is that it uses the data tagged to music and video files to pull down info and details from the Zune store. The application saw that I loaded the newest Lamb of God album on the phone and automatically pulled down the bio for LoG and a list of the band's other albums for sale in the Zune store.
Music sounds great pumped through my favorite headphones, and video looked great on the screen. I do wish the 900 (and Windows Phone) played better with my iTunes video content, though.
