You can't. But you can from rhapsody. Or by downloading samsung studio 3 you can get music on the phone from other sources other than itunes.
You can get a sd card transer files to there then put sd in phone then save
As I know, the music files downloaded from itunes have drm license protection that prevent users playing itunes content on other non-apple mp3 player and cell phone, if you want to put itunes playlists to play on samsung phone, you may need to convert itunes files to mp3.
