I was going to put this post under 'Computers and Internet' but then it's really about music on a computer and more importantly the DRM.  The Artilce is from SysInternals by Mark Russinovich  a very talanted windows engineer that I have always respected his views.  Basicly he noticed after playing a CD in his computer that the CD's Producer had installed software on his computer that he could not only uninstall without great diffculty but the software was hidden and took some investigation to sort out.

 

Rather than me giving further details, have a read of the articles below:

- Sony’s Rootkit: First 4 Internet Responds

- Sony: You don’t reeeeaaaally want to uninstall, do you?

These are quite detailed articles but an interesting read, make your own mind up following this read......
