New Radio buttons discovered in iOS 6.1 hint that a new 'iRadio' service aiming to compete with the likes of Spotify and Pandora could be on its way to iPads, iPhones and iPod touches soon.

9To5Mac reports that it came across a new set of files in the iPad Music app after jailbreaking the device this week. These files are called 'radio button', with an icon that resembles the radio icon that could be found in iTunes for the Mac in the past, with the same antenna tower.

The button files also have the word 'buy' in the filename, indicating that new Radio functionality that could be subsctiption-based might be in the works at Apple.

The discovery suggests that Apple could be planning to launch a new music streaming service, dubbed 'iRadio', which past reports have claimed could be a personalised service that aims to take on Spotify and Pandora. Several reports have suggested that Apple is currently in talks with music labels in preparation for the launch of the so-called iRadio this year.

When iTunes 11 was released late last year, the introduction of a new dedicated Radio button also led to speculation that Apple is working on iRadio.

Apple's iPod nano already has the ability to play FM radio, a feature that includes Live Pause functionality and iTunes Tagging, which allows users to preview and purchase tracks in the iTunes Store on supported stations.
