Google Music has a feature called Instant Mix that'll create playlists for you. It's kind of like Pandora, only limited to your own music collection: You select a specific song, then Google Music goes through your library and picks out other songs it thinks would go well with your choice.

Google's movie-streaming service lets you rent a movie from the Android Market, then watch it on the Web or on your Android device. Once you rent a film, you have 30 days to start watching. After you click "play," the movie's good for 24 hours; during that time, you can view it as much as you want from any PC or compatible Android device. You can even watch it via YouTube, if you're so inclined.

As of now, the Google movie service is available only in the U.S.
