In the beginning, Windows Media Player was the headquarters for music and video on your PC. It was the Grand Central Terminal for things like music CDs (you could play ’em, copy songs off ’em, and burn ’em); MP3 files and other digital songs (you could sort ’em, buy ’em online, and file ’em into playlists); pocket music players of the non-iPod variety (fill ’em up, manage their playlists); Internet radio stations; DVD movies (watch ’em); and so on.
Media Player still does all that, and more. But it’s no longer clear that this is the program you’ll use for these activities. Gradually, the Media Player audience is splintering.
