I should seriously be asleep right now, but I am more than a little addicted to WebJay, and I have spent two hours playing with it and learning how to tweak playlists. WebJay is great for making downloadable/streamable/shareable music playlists. It even provides a player that you can embed in your blog or web page, which streams your playlists much like the MySpace player streams your songs. It's really awesome, it's free, and it's pretty damned easy.

I have my player posted on my MySpace, or you can check out my playlist here.
