Sony and IBM have announced that they develop a copy protection for internet music. This is a further step against the abuse of copyright protected music files. The OpenMG technology works as a copy protection on the local PC, while the MagicGate technology is the internet music access system. Because of a problem of the assembling company the date of the final release will be shifted forward for one month. The first 100 buyers of the product will get an information about the production status the next days.

Nullsoft probably will have to show their source code. MS-Audio not as good as claimed. One thing is for sure, also MS-Audio can perform miracles. BUT songs of this size probably don't sound any better than equivalent MP3 files. So there's only the security aspect, where MS-Audio is better than MP3.
