I have about 7gb of music in my iTunes library. I have about 250gb of music in folders outside of iTunes. I have an 8gb Touch. When I want to add music from the 250gb, I delete some from the iTunes library first and then add the new ones. I want to do iTunes Match but I need to know what music I can upload. Does it have to be only from the iTunes library (7gb) or can I point to other folders and upload my entire 250gb? I don't want to have to move the 250gb to iTunes because then I obviously can't sync it to my Touch.
