On my MBP, I have my iTunes library and all of the tracks on an HDD attached to my AEBS. In preferences I have the iCML turned on. It has uploaded or matched my tracks. Great...so far, everything looks good. So my understanding is that I should be able to listen to my iTunes tracks when the NAS is not available through iCML. To test it, I turned off the HDD and tried to play a track from iTunes on my MBP. First, it gives me a popup asking me to connect to my AEBS. I hit ok and that disappears, then I get a message saying it can't locate the track because it can't locate the file. It asks me if I would like to find the file. I hit cancel because I know it can't find the file, the HDD is off. After I do that, the track starts playing, so I have to assume it is playing from iCML, right? The big problem is, I have to go through this whole sequence for each track I ask iTunes to play. I know this can't be how it really is supposed to work. Does anyone have any suggestions to improve the situation?
