Youtubify, a Spotify clone with YouTube as back end (youtubify.vebto.com)

The site completely breaks the back button

I think this is interesting from a legal perspective, and quite impressive.

Either YouTube shuts off API access or they get hit with a lawsuit. Nonetheless, this is a very cool idea and excellent execution!

YouTube's rules have something against not displaying the video.

This will need to be updated to display the video to stay up.

Would love to see this as an official part of YouTube! YouTube has large amounts of music that is hard to find anywhere else online (vinyl only, etc). For listening I usually make playlists on YouTube, but this is incredibly clunky.
