Microsoft PlaysForSure

[5] Microsoft announced that as of August 31, 2008, PlaysForSure content from their retired MSN Music store would need to be licensed to play before this date[when?]

[7] With the exception of Windows Media Player, all of the PlaysForSure offerings were made or run by 3rd-party companies, while Microsoft's Entertainment and Devices Division developed and marketed the Zune.

A 2005 court case strongly criticised the wording of a Microsoft licensing agreement related to portable devices.

[9] The license prohibited makers of portable devices compatible with Windows Media Player from using non-Microsoft audio encoding formats.

Microsoft quickly amended their stringently worded license agreement at the judge's behest.
