Free Music Downloads for iPhone? - 1

I was wondering if I could get the songs "Forever Young" and "Torn" One Direction covers free from the Internet or something. My friend has got them on her iPod 5th Generation and I have no idea how! Any ideas/help?

On your computer check if the song is on YouTube.
Then, go to www.listentoyoutube.com
