How do i put music on my mp3 player

just bought mp3 player don't know how to put my music from my library on it. when i plug it into computer the songs are on the mp3 player but they won't play.

if you already have songs in your computer

connect your mp3 player it will say open folder answer yes, then click on the corner to lower or move your window drag your song from your computer folder to that window usually e or f. to drag the song you need to click and hold down your left mouse button on your song and move it to your e folder then release button.
another way is by click right button on song then choose copy from the list then go to your mp3 folder e and right click then paste.

Open the folder that contains your music. Right-click which song you want to add. Select send-to and select your device from the list. Hope this helps.
