The only time I've found myself wanting autoplay is when it's an obvious playlist, such as TV shows on Netflix or explicit playlists on Youtube.

All of the other times, it's really just irritating, and I've only gotten more annoyed lately because of it. Netflix just promotes its newest shows, and frankly I don't watch that many Netflix originals. Youtube... the recommendations are fine, but the next video selection is very little hit and mostly miss for me.
