The feature will allow users to stream a song for 30 seconds by tapping and holding the artwork on an album in a playlist, genre or album tracklist, and seamlessly scroll to activate the next sound by moving to the next song anywhere on the screen.
Users can scroll up and down and leave their finger held to a specific song they would like to listen to longer, or maneuver through different ones until they land on the desired one. Once you have found the song of your liking, they can swipe right to queue it or swipe left to save it to the library.
