Some media players show pop-up notification on the desktop whenever the track changes even if the media player is minimized or not in focus. I’m not particularly fond of those, but if you are, you will love the Now Playing notification for videos playing in YouTube. If you are wondering why one should need notification when they can see for themself which video is playing, you are forgetting that YouTube is the most popular destination for listening to music.
Most users will load a video album playlist, click the play button and minimize the browser or otherwise carry on surfing. With YouTube notification, these users get the same functionality they get from their desktop media player. And here is the interesting part: these notifications are displayed on the desktop, out of the browser.

Whenever a new video loads from the playlist, a small window pops open near the notification tray displaying the title of the song. The notifications stays just long enough for you to notice and disappears on it’s own.
