3 Ways to Download Free Music to iTunes
To actually download the free song to your PC, so you can add it to iTunes or put it on your phone, you’ll need to open your Google Play music library. To do this, go to the Google Play music page and click My Music. Under Recent Activity you should see the song or album you just downloaded.
Click on the thing at the top left that says “file”; and it should say “add song to library.” Locate the song you want to add to your iTunes library (which could be either in the downloads or music section), and click on it; select “open.” It should then be in your iTunes library.
