USB cord

Open the folder which you downloaded the music in and then plug your iPhone into the computer and if you see an iPhone icon then drag the music to the iPhone icon and you should have the songs you downloaded on your iPhone or if your music is from iTunes it is basically the same process

Yes. Through iTunes.
