The lowly MP3 music format was quietly replaced by MP4. But this week, there’s news that a Chinese company has introduced the world’s first MP6.

The company is AIGO. We haven’t heard much of it here in the US. but we soon will. The device that plays the new format is the eMusicPlayer, using a wireless “reading-point pen.”

What’s interesting is how it blends the technology with a publishing concept. Aigo will publish a ‘music magazine’ periodically,  with about 200 to 300 songs. The pen is then used like a mouse, to point and select the music from the magazine.

I could see audio book publishers, and podcast aggregators putting this to great use. Of course any music player that can download a file wirelessly has a big advantage.
