Mobile-based music recognition service Shazam has arranged a new $30 million investment (around £20 million), which values the company at over $1 billion (£663 million).

The company has over 100 million active mobile users per month and has seen its app downloaded over 500 million times.

Shazam, which enables users to identify or ‘tag’ music tracks and learn more about TV shows via a smartphone app, has predicted the music artists that it expects will ‘break’ during 2014.

Overall, more than 400 million people use Shazam worldwide, with more than 15 million Shazam searches taking place every day.

Media engagement company Shazam, which offers a mobile-based music identification service, says its free mobile app has now been used more than 10 billion times to identify and ‘tag’ songs, television shows and TV ads.

The 10 billionth song was ‘Applause’ by Lady Gaga, which was tagged on an iOS device in the US state of New Jersey.

We start this week's podcast by talking about an Android security risk - before moving on to new 4G services from EE, a drop in Nook tablet prices and a couple of quarterly results that disappointed the stock market.

In addition we discuss insurance complaints, Bluetooth Smart technology, a new multi-million investment in Shazam and some research about the future of apps.

America Movil, which is Latin America’s largest mobile telecom network operator, has invested $40 million in mobile music recognition and media engagement company Shazam.

The money will help accelerate Shazam’s growth as well as funding the development of new products.

A suggestion that UK mobile phone networks might be forced to improve black-spot coverage by allowing interconnection with their rivals is back in the news. It made the headlines in June and has returned again this week, which is why I could be heard offering my opinion on BBC local radio yesterday morning.

If I'm interviewing someone for a podcast, I'll generally use my Zoom H4N recorder and a separate microphone or two. But I don't need the same level of high-quality kit if I'm interviewing someone for a written interview. Why carry an expensive recording device when your mobile phone can do the same job?

Contactless payments. They're catching on, aren't they?

But mobile contactless payments haven't proved so popular.

I open the iPhone 6 box and discover a phone that feels substantial. Well engineered. Practical. Despite being just 6.9mm deep, it doesn't seem unreasonably delicate.

Following my online rant about the customer service I'd received when I suffered a problem with my HTC One, I wrote to Carphone Warehouse.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
