⏫Fast Up Button emoji is used to speed up a video or some music. Don’t confuse this with the fast forward option since this speeds up the sound instead of the image. If you enjoy listening to high pitch songs or videos, than this is the button for you. Combine it with a 🎵 Musical Note emoji to show that you are having some 😄 Fun tampering with music sounds. Or if you need someone to hurry up with their speech, send it with a Dash Symbol emoji..
