To transfer music to the Sansa, use the included USB cable to connect the player to either a Windows or Mac PC. Note that you'll need to first select the mode--MTP or MSC, respectively--in the settings menu. Mac users can simply use the drag-and-drop method in Finder to transfer artist or album folders to the player's music folder. Windows users have a choice of transfer methods: use drag-and-drop or a WMA jukebox such as Windows Media Player or Rhapsody. The Sansa is compatible with MP3s and both protected and unprotected WMA files. The player supports playlists as well.
