An anonymous reader writes to tell us that Bach Technology has rolled out an updated MP3 file format in a bid to combat music piracy. Dubbed "MusicDNA," the new format offers embedded "updatable premium content" like lyrics, videos, news updates, and album artwork. "Using the new technology, music labels and bands will be able to send updates to the music files – with tour dates, interviews or updates to social networking pages – while illegally-downloaded files remain static. ... No major labels have signed up to use MusicDNA so far, but British record company Beggars Group and US label Tommy Boy are both on board. However, the files are likely to be more expensive than MP3 files – according to the BBC – and will have to compete with Apple's iTunes LP, which already provides additional content such as bonus tracks, lyrics and video interviews."
