After the fiasco that Microsoft experienced when they made the announcements that they would turn off the MSN Music servers one would have thought that other companies would not follow that lead and would have learned a lesson from it.
Microsoft backpedaled quickly after it became apparent that the public was not that pleased with their decision and decided to keep the servers up and running for another three year period. The huge problem that arises when DRM servers are taken off the Internet is that the verification process will fail which means that users who want to move the music from an old to a new computer - where they had to verify the music again - would realize that they could not do so because of the server being offline.
Yahoo apparently did not pay attention to the media fiasco and decided to close the Yahoo! Music Store and take the DRM servers offline on September 30, 2008.
