Adding songs to iphone 4s without itunes?

How can I add songs to my iphone without itunes. I recently got a new computer so if I download Itunes and plug my phone in I will lose all my songs. Are there any ways around Itunes? Or anyway around not deleting my songs?

You can transfer all of your songs from your old computer to your new one. First download itunes.plug in a thumb drive or SD card and move the itunes folder onto the thumb drive/ SD card. Now you put the itunes folder with all of your music on your new computer and replace the empty itunes folder with the one with your music. All of your music will be on itunes when you start it up.
