Welcome to iMore. The object of iTunes is not to get free music. It is so you can purchase music & apps. Here is a [URL="https://www.apple.com/ca/support/itunes/getstarted/#mn_p]link[/URL] on iTunes and its uses.
Welcome to iMore! Downloading "free" music is usually illegal and not something we condone here. You can pay $9.99 a month for Apple Music and listen to your heart's content. It's worth it!
