If you want to take advantage of Google's wide selection of movies and music, there's no need to get a Chromecast or a Nexus Player; Roku can access them, too. The Google Play channel offers TV shows, films and music that you can rent or purchase one piece at a time. In addition to providing both SD and full HD videos, the service also offers competitive prices and information about actors in real time. Best of all, Google Play gives away movies and albums all the time. Recent freebies include X-Men, The Fellowship of the Ring and the Guardians of the Galaxy soundtrack.
