Hi there, I was wondering whether someone here can help me out. I've read conflicting reports both here and over the web as to this, so I thought it would be best to check here to see if someone can help me out: I have Windows PC with about 120 GB of music; I have a 64 GB iPhone and 64 GB iPad. I would really like to get iTunes Match, but I'm concerned as to whether the music I already have on my devices will remain there. I have some 40 GB of music on each device and that's important to me because I don't always have access to Internet. I'm in the subway, frequently, and when I travel, WiFi is quite limited. SO, if I subscribe to iTunes Match and finish through the process on my PC, will the music I already have on these devices remain there? Currently, they have been synced from the same PC from which I would like to subscribe to Match. Thank you all for your time and insights.
