YouTube was once a simple service. You simply uploaded your videos to the platform or watched videos other people uploaded. However, it has since diversified its portfolio, so to speak. Here is everything in YouTube and what it does.

What's the deal with YouTube Music?
Easy transfer and transition
The service provides ad-free access to content across the service, as well as access to premium YouTube Originals programming produced in collaboration with the site's creators, downloading videos and background playback of videos on mobile devices, and access to the YouTube Music music streaming service. The service was originally launched in November as Music Key , offering only advertisement-free streaming of music videos from participating labels on YouTube and Google Play Music. YouTube announced the rebranding of the service as YouTube Premium on May 17, , alongside the return of a separate, YouTube Music subscription service. The service was first unveiled in November as Music Key, serving as a collaboration between YouTube and Google Play Music , and meant to succeed the former's own subscription service. Music Key offered ad-free playback of music videos from participating labels hosted on YouTube, as well as background and offline playback of music videos on mobile devices from within the YouTube app. The service also included access to Google Play Music All Access, which provides ad-free audio streaming of a library of music. During its invite-only beta, Music Key faced mixed reception due to the limited scope of the offering; YouTube's chief business officer Robert Kyncl explained that his daughter was confused over why videos of songs from Frozen were not "music" in the scope of the service, and thus not advertisement-free. This shift required YouTube to seek permission from its content creators and rights holders to allow their content to be part of the ad-free service; under the new contract terms, partners would receive a share of the total revenue from YouTube Red subscriptions, as determined by how much their content is viewed by subscribers. YouTube also sought to compete against sites such as Netflix , Prime Video and Hulu by offering original content YouTube Originals as part of the subscription service, leveraging prominent YouTube personalities in combination with professional producers.

The transfer process can be done with an Android device, iPhone, or from the web. You can also initiate the transfer from YouTube Music on the web — both on mobile and from a desktop browser. The two services do not sync content. I really love Google Play Music! How much longer do I have to keep using it? Moving forward, you can expect to see messages like the one below in Google Play Music.
Don't worry, Google now has an easy way to move your music library, playlists and preferences over to YouTube's music streaming service. But YouTube Music recently unveiled a tool to help you transfer your entire library, profile and playlists from Google's streaming service into YouTube's revamped one with just one tap. YouTube Music is also getting some new features that may make it a bigger competitor to streaming services such as Spotify and Apple Music. For now, users will have access to both services, giving them time to move their music over and get used to the YouTube Music interface.
