JonChurchill You can use Google TV for content, and Spotify or YouTube Music are my top two choices for music. For iCloud you got Google Drive or OneDrive, Google Photos for iCloud Photos backup (G Photos syncs photos to G Drive).
Also, you got some other TV/Movie providers such as Amazon, Netflix, BBC iPlayer (for free, if you are in the UK and pay the TV licence), NOW TV (again if you are in UK, and watch Sky content).
