Making for the collaborative creation of YouTube playlists is what this site is all about. On B00mbox, you can put one such list together by creating a slideshow to which everybody can contribute.

The actual uses something like this can have, now, are as many as people walking this Earth. Coming up with the best songs by this or that band and creating lists of the best movies to watch when you are feeling exultant (or broken-hearted, or whatever mood you could think of) are certainly the most obvious uses that spring to mind. Yet, uses such as gathering together the best menacing looks Humphrey Bogart gave in his career are likewise made possible. And they are every bit as respectable, too.
