The website Finetune allows you to create streaming radio stations tailored to your specific tastes. Their catalog of songs is extensive and includes every major label in the US as well as many of the bigger independent labels, making it easy to find the songs you want. Finetune requires that each playlist must be at least 45 tracks long and cannot contain more than three songs by any one artist; these rules enable the site to operate as an Internet radio station as opposed to an on-demand music service. Once a playlist is finished, Finetune generates a piece of code that you can copy and paste to another website -- a blog, a MySpace page, etc.-- so that your playlist can be available anywhere. I've included one I just made. Want to take a shot at making your own? E-mail me your code and I'll put it on here!

Update: I have installed my Finetune widget permanently on the sidebar. Again, if anybody else wants to take a shot at creating one, I can install yours on here too!
