0.2 Generate iOS Push Certification for One Signal iOS Device.

1. Add Notification Service Extension

1.1 In Xcode Select File > New > Targe

Scrobbling does not currently work from the YouTube TV web browser interface (available at https://www.youtube.com/tv). This web interface is the only official way to remotely control YouTube, so it's ideal for playing music videos on a computer from a phone. It would good to be able to scrobble it and as it uses predictable artist and title patterns, it shouldn't work too differently to YouTube.

When using Subsonic (or compatible server), a scrobbler can be configured in personal preferences. This means that you can configure the scrobbler once and supported clients will use it. The client-side configuration is as simple as checking a box. The client starts playing a song and the Subsonic server takes care of sending the info to the scrobbler service. In Airsonic, ListenBrainz and Last.fm

Is it possible to add this method, based on the existing Artist.GetTopAlbumsAsync but with Mbid ?

Considering this project has ended maybe it would be fair to update the readme to make that clear.

Perhaps making it a little bit more informative on what the code does too, doesn't need to be very long.
