A new music file format has been unveiled by some of the key figures behind the development of the MP3.

The new file - called MusicDNA - is a vastly more complicated version of the mp3 and can include things like lyrics, videos, artwork and blog posts, which will continually be updated, as well as the music.

It has been created by Norwegian developer Dagfinn Bach, who worked on the first MP3 player in 1993 and its investors include German researcher Karlheinz Brandenburg, who is credited with inventing the MP3.

British record company Beggars Group, whose labels are home to Vampire Weekend, MIA and The Strokes, has signed up to use MusicDNA, as has US label Tommy Boy. However, as yet no major labels are currently on board and the MusicDNA files are likely to be significantly more expensive than current music downloads.

It will also be in competition with Apple's iTunes LP, which gives users added content including bonus tracks, lyrics and video interviews.
