How to stransfer my downloaded music off of my laptop to my iPhone?

I have downloaded music on my laptop and tried transferring it from iTunes to my iPhone but it won't do anything. Isbit bc it's not legall? Or I'm just doing it wrong?

Okay so i had the same problem with my music. A common mistake people make is not "syncronizing" their ipod / iphone on itunes. If you don't do that it basically does not save anything pictures, music… Etc. Click and drag the songs onto itunes and then goto the top left corner of your itunes and click the first button, then scroll down until it says sync ipod. And there you goo

You need to drag the music files into the iTunes music library, the place where you can play songs like Windows Media Player, just drag into there and iTunes will automatically store it in their library, afterwards you can sync the songs by looking for the name, artist, or album for synchonization, the only problem is iTunes will remove songs from your iPhone if its not found in your own library due to copyright issues.
