If you’re on your mobile device or at your computer, you can share your own playlists or ones created by other YouTubers. When you share a playlist, a link is created that you can give to somebody else. You can share it on social networks like Facebook, Twitter, and Google+.
Remember that if your playlist includes any private videos, you'll need to invite your friends or family to view the videos first.
To share a playlist, click the Share button on the Playlist page. From here you can share the video across social networks, embed the video, or email the video.
You can also share a playlist while watching it. Click the share icon under the video. From here you can share the video across social networks, embed the video, or email the video. You also have the option to share the playlist from the current video you’re watching or from the start of the playlist.
If videos aren’t appearing in an embedded playlist, some of the videos in the playlist may have had their embed option disabled by the uploader. Private videos will also not play in the playlist unless they've been shared with you by the uploader. For best results, you may want to ensure that the content you've included in your playlist contains only public videos that have the embed option enabled.
