I'm 110% all for supporting the artists and NOT the media corporations. There are too many problems with this idea.
I might be missing something here, but I could see how this new format be interesting to indie artists that rely on the distribution of their music for absolutely free and without compensation, but rely solely on having their fans attend their concerts and buy their merchandise. I can't see anything wrong with unknown artists wanting their concert and merchandising info to be fed to their music files in the hopes to earn a living.
But, why not create MP3 ID4 that will do this instead?
I would NEVER support such a thing if it were flogged by Sony/WMG/EMI/etc. Fuck them.
As for the DRM. Indie and unknown artists need to understand that DRM will only destroy their chances. I'd also be concerned if the streaming information content distribution of this MusicDNA got hacked it could wreak havoc upon their fans and will drive them away permanently. That is very very dangerous.
In addition, what if someone created a virus that hunted down MusicDNA music files and hacked them to become spam relays or part of a botnet? What if they were hacked to spew porn, pharmaceuticals, gambling spam instead?
As a general rule, ANY closed format file is very bad for business.
