My husband and I are both having a similar issue on our Droid phones. After ending a call while on our bluetooth headsets, music will start playing. We both have stock phones and have updated to 2.2. We do have music on our phones but don't normally listen to it. We are not listening to music prior to the phone call. On the rare occasion when we do listen we use the standard music app. This did not start until after updating to 2.2. Any suggestions on how to stop the music from playing after a phone call?
