Google has revealed three new Nexus-branded Android devices and an update to the Android mobile operating system. Its announcement was made online after a planned press conference in New York was cancelled due to the threat from Hurricane Sandy.

The new devices are expected on 13th November and will run Android v4.2, still known by the same codename as version 4.1: ‘Jelly Bean’.

Microsoft is introducing a new online music service that uses the company’s Xbox brand, replacing the previous Zune branding. It’ll appear as part of an update to Xbox games consoles from Tuesday and will also be available on Windows 8 devices when the new OS launches.

Xbox Music will include a free music streaming service, a subscription service and an online music shop.

Music discovery service Shazam has announced that it’s exceeded a quarter of a billion users worldwide.

Last month the company revealed that its service had been used to identify over 5 billion songs, TV shows and ads since launching.

Shazam, which was created as a UK-based music identification service using the ‘2580’ short code ten years ago, has reached a new milestone. Customers have now used the service to identify songs and to learn more about television shows and ads over five billion times.

The Shazam app is currently used ten million times a day by a fan base of 225 million people.

Amazon.com has updated its cloud-based music player - which is currently only for US-based customers - by giving it the ability to ‘scan and match’ music from other sources. It means the service will have similar abilities to the streaming music players offered by Apple iTunes and Google Music.

In order to offer the music matching service the company has signed  agreements with Sony Music Entertainment, EMI Music, Universal Music Group, Warner Music Group and more than 150 independent distributors, aggregators and music publishers.
