I don't want to go through the madness of having Itunes Match upload my entire library only to have some of the songs messed up and since I don't care about streaming, only having 256 kb songs, I wanted to only have Itunes Match take the 128 kb songs in my library. I figured the only way to do this was to create a new library, I did that with the Option key during Itunes start up, I then moved the 128 kb songs to a folder on my desktop. I will then move those songs to the new library. My question is, if I start Itunes Match when logged on to that new 128 library, will it leave my 256 library alone? After I am finished with the 128 library, I will change Itunes match to not work automatically, I'm hoping then when I log onto the 256 main library, it will leave those songs alone. Has anyone had experience with 2 separate libraries and Itunes Match?
