How do I Play Music on my Smartphone?

First you will have to buy the special cable from the manufacturer of your particular Smartphone which plugs into your charger, then into your computer. Some people just charge their Smartphones directly through the computer anyway. If this is the case, then you just open up my computer, then click on the drive that correlates with your Smartphone. You should have a music directory, if you do not see it look in My Documents. If you still do not see a music directory anywhere, just right click inside of My Documents, choose the new folder option and call the new folder My Music. Then you just drag and drop the music you want from wherever it is on your computer to the My Music folder. Then you just plug headphones into your Smartphone and go to the My Music folder and click on the song and that's it.
