I have short questions about iTune Match. 1. Do we really own the music files? It is really on computer and iDevices? Or it is steaming music service. 2. Can those music files be synced freely between devices? Etc. Androids 3. Is it actually a music file there like we bought songs from iTunes music store? 4. What happen if I cancel the subscription? Do I still own it? Or music files are gone?
