This week, Yahoo Music e-mailed customers who purchased music from their site and let them know that as of September 30, 2008, Yahoo Music will go dark.
And they will take the DRM key servers down with it.
That means that anyone who legally purchased tunes through Yahoo Music will lose the right to transfer that music to other devices or computers, even though they paid for that right.
Microsoft's MSN Music sent a similar notice out earlier this year, but acquiesced to leaving the DRM servers online until 2011.
Once again, this truly provides food for thought for libraries signing up for content services who cripple their wares with DRM. When they decide to leave, they can take their toys with them. Unfortunately, they can also take your toys with them too.
