Microsoft followed up Nintendo's surprise Wii U GamePad announcement on Sunday by unveiling a new Xbox Music service and SmartGlass streaming app at its E3 press conference.

In its goal to make the Xbox 360 360 more than just about gaming, Xbox Music will give users access to over 30 million tracks with a unified app that works across the 360, PC, Windows 8 tablets and Windows Phone 7 smartphones.

Details of the SmartGlass app leaked earlier this week, and Microsoft confirmed its existence explaining how users will be able to watch a film on a tablet and then beam it to a TV to continue watching from where you left off.

Users will also be able to access content like cast information on the tablet while watching the film on the TV. Microsoft also demonstrated its potential for gaming with a series of concept videos showing the app integrated into Halo 4 and Madden 13.

As well as Windows phones and tablets, the SmartGlass app is expected to be available on Android and iOS, however Microsoft did not name any specific devices as part of the announcement.
