I just recently added a folder as new source in local files. I saw the folder registered in the local files setting =Show songs from "C:\user\abcdefgblabla" ---that's my new folder. I chose =do not show songs from...= other folders in my computer. However when I went back and clicked on "local files" hoping to play my new added songs from abcdefgblabla they were nowhere to be found. But the old songs, those I chose not to be shown on the list were there.
