iTunes 12.1 - Stuttering when playing music
Many iTunes for Windows users had the same problem with the recent upgrade, myself included. To fix the problem (it worked for me), download and install the iTunes 12.1 for Windows that is supposed to be for older video cards. But don't let that last part fool you. I have a card less than 12 months old and this solution worked wonderfully. Here is the link to the download from Apple: http://support.apple.com/kb/DL1784?viewlocale=en_US&amp;locale=en_US.
