1. Navigate to www.amazon.com.
2. In the search box, select "MP3 Downloads."
3. Click the "Go" button. Results appear ordered by "Bestselling."
4. Select "Price: Low to High" from the "Sort by" menu. The first several pages you see will be free music.

If you're not sure you'll like a free song, click the play button to the left of the Song Title and listen to a sample. If you're still not sure, download it anyway. You can always get a refund. LOL
