[Request] Youtube Playlist

Hey i was wandering... you know this apps that allow IOS users to repeat play videos from YouTube, either music either what they want, my request is about logging in the YouTube account, loading your playlists, and then either choose a video to play or just play all playlists from top to bottom, on repeat or shuffle. any idea if its even possible?

not sure, i seen a few youtube mobile players, but what they do is just load each video link as u search for it as many websites repeat youtube video do, what my request is, making a area for login or register to youtube, load your playlists and automatically play them as you do in youtube, but it could be used for mobile, pc etc . its taking so much of resources of using youtube online, it creates a big cache, so by running it from pc will be easier... and less resource eating.
