I assume you mean Windows Media
player? and not the compression format? not quite sure if this was a question about formats (with winamp == mp3) or players.
But, as SiN said, your question is a bit vague... although I am ashamedly a big fan of Windows Media Player, over Winamp.
I really like how Media Player will display the cover art of whatever album you're playing. And if you're playing an MP3, it displays "folder.jpg" from the folder where the mp3 is (if it exists). I also really like the pull-down menu which lists all your playlists, cd-rom drives, artists, and/or albums, which you can customize. Not to mention how the taskbar entry turns into a mini control panel when you minimize it.
Yea, I like Media Player.
