It stills works, you just don't have the plug-in installed for it. If your using Windows, you need to download a newer version of Windows Media Player or assign the MP3 extension to Quicktime or RealAudio. Windows Media Player didn't support MP3 until version 6. The newest version is 6.4 and version 7 is in beta. V7 will not work on Windows 95 or NT 4.0 though.
