Netflix can be adjusted from the Desktop site, YouTube from within the app, other streaming services similar I'm sure. Same goes for Internet radio and cloud music players. Make sure you go through your apps listed as using data in Data Use in the main phone settings menu and restrict background data for apps you do not want to use data unless they are in the foreground, and actively being used.
