If you want the extensive media features of Plex but without the hassle of setting up a Plex Server there is Plex pass which has just come out of beta. With Plex Cloud you can store your music, videos and photos in Dropbox, Google Drive and OneDrive and then access it from Plex. This means you can stream all your media to the wide range of Plex apps including Android, iOS, Xbox and Windows.
To get started with Plex Cloud you need to be a Plex Pass subscriber.
