Can i put songs from my ipod touch ( that I bought on the itune store there) to my itunes library?

well i don't see why you couldn't, simply connect the ipod touch to the computer then click file then click transfer purchased items, and anything that you bought on the touch should go into your itunes library...

i prefer to propose AVCWare iPod to iPod/computing device/iTunes flow which could flow your iPod and iPhone song, video, playlist, pictures back to computing device and iTunes. in case you very own extra desirable than one iPods, AVCWare iPod to iPod/computing device/iTunes flow can concurrently take care of all of the iPods in the comparable interface, you are going to be able to flow information between those iPods by capacity of drag-and-drop. desire it facilitates!
