Webjay is a tool that helps you listen to and publish web playlists.
MP3 players like WinAmp, iTunes, RealOne, and Windows Media Player can be given a list of songs to play. Most of the time the songs are on your computer, but they can also be on the web. Webjay is all about playlists of songs on the web. Playlists that link to web-based files are portable -- anyone with an MP3 player and an internet connection can create and swap playlists without having to transfer the actual songs themselves. This means you can email your small playlist file (actually just a specially formatted text file) to your friend, post it on your web site, or take it with you to work.
