I went into the synch area of Windows Media Player and marked a bunch of my music file not to synch any more. So I figured on the next synch of my Droid X (Android 2.1) the corresponding files that were already on the phone would disappear. But they didn't. Shouldn't they? Do I have to go through and manually delete them one by one from the phone? Frankly, I'm not sure Windows Media Player's approach to setting up a synch list makes sense at all. Is DoubleTwist or WinAmp less confusing?
