So, I made a little web-app that uses youtube as a back-end for a music player. Pretty simple concept, pretty simple execution. You can check it out here: http://shinmera.tymoon.eu/public/YMWA/ It currently only works in Chrome and Opera, as Firefox is apparently too much behind the times to implement the HTML5 input type elements (range, in specific). I'll see about a workaround though. I won't even bother with IE. How to: You can add tracks to the queue by typing in the video ID and hitting enter/pressing the plus sign. Deleting tracks works by selecting them in the playlist and pressing the delete key. Simply double click an entry in the list to play it. The repeat button will repeat the same song over and over and shuffle will continue to select a random song every time one ends. I'll add a playlist repeat mode and proper shuffle implementation later.
