Prolific YouTube users know how difficult it is to preserve the links to their favorite videos on YouTube. And even as you are playing several of them at a time (for example, while you are searching for videos), managing the multiple windows can be - to say the least - maddening.

Enter PlisTube (beta), the cool web application which solves the problem by letting you create video playlists of your favorite songs and artists, primarily from YouTube. Or even better, it helps you build on top of popular playlists created by other users. All of which you can get done in your choice of language - English or Spanish.

Creating a playlist on PlisTube is best described as child’s play. Once you have signed up for the service (it is free!), you start off by entering the name of the song/artist in the search box. PlisTube then lists thumbnails of all the relevant videos available on YouTube. Choose from the videos listed in the search result and add to your favorites. Voilà! Your playlist is immediately updated. Once created, you can even share your playlist (via the URL) with your friends. That’s BlissTube for music buffs like yours truly.
