Microsoft and Apple DRMs Cracked [update]

Convincing Music Majors that DRM-protected music tracks were the way to go to sell music on the net, while being a rock solid and un-crackable protection, was probably the most difficult task for Microsoft and Apple representatives. This is also the reason why Apple has always been quick in modifying iTunes every time the FairPlay DRM was bypassed.
Within the last days, we have receive reports proving that one can efficiently bypass DRM-protected WMA or AAC files. Of course Microsoft and Apple will quickly react in the coming days.
Eventhouhg Apple own over 70% of the market of online music business, Microsoft is probably more in danger than Apple if they can not quickly correct their DRM on WMA files. Indeed, many providers of DRM-protected music, with unlimited download but monthly fee required to listen to music, such as Napster, use DRM-WMA system; so a user can massively download the music catalog, then unlocked all tracks. It would be the fastest way to get a very large music collection for a ridiculously low cost.
[update] On August, 30th, Microsoft has already modified its DRM system Playsforsure to patch the problem.
