Finding Music Key Enabled YouTube Videos

When Google announced YouTube Music Key, I expected that mobile users will be able to download and play in the background almost any music video. Unfortunately, these features don't work for many videos, especially for music videos from unofficial YouTube channels.

It's easy to tell if you can download or play in the background a video: look for the download button in the mobile YouTube app.

If the download button is there, you can tap the home button and the video will continue playing in the background.

For some reason, YouTube doesn't offer a search filter that allows you to restrict search results to videos you can download and play in the background. A good idea is to play YouTube's mixes or pick an album from the music card, when searching for an artist.
