Quick tour of Nokia Music app for the Lumia series [Video]
So not a lot has been shown of Nokia Music, their free app that will be on board the Lumia 800 and 710. Think of it as a Zune II but without the cost. Basically you get to find music, stream it and create playlists. In addition there are pre-made mixes, similar to 8tracks--you can even save them for offline playing. If you want a song, it takes you to their own music store where you can buy tracks individually. Finally, you can even browse for upcoming concerts, which was a nice touch as it adds Eventful like functionality to the app.
Overall a nice service which will augment Zune.
