Can Songbird use and keep track of its own independent library?

Is there any way for songbird to use an independent library, that is independent from itunes? I want to use songbird as a replacement for itunes. How can I keep a folder called songbird music, instead of itunes music, so that when i make changes in songbird, it changes the files themselves? As far as I can tell, songbird dosn't keep its own library, it just plays music that you tell it to. I want it to copy the files that I import into its own folder, not just play files from another. I dont know if this makes sense, its hard to say what im trying to do, but any help would be greatly appreciated.
