When you are listening to your favourite music on your Samsung Galaxy S4 or other Android phone or tablet, you might want to share it with your friends. This is especially true if it is something new that you have just discovered or a new track or album that your friends may not yet know about. You can share the music with them and let them know how good it is and what they are missing.
The track menu: When there is a track playing or a list of tracks, tap the menu button in the top corner of the screen and select Share.
Use Google+: A Google+ window appears on top of the music player with the album track artwork already attached to it.
Add a message: Tap in the text box and the keyboard appears so you can enter a message. Press Share afterwards.
