just uploaded 50 CDs from my iMac to my iPhone. How can I set up a favorites list?

Hi 112647jimmyg,

If you have synced these albums from iTunes to your iPhone, you should be able to create a playlist in iTunes for your favorite songs or albums, then sync that playlist to your iPhone as well. You may find the information and steps outlined in the following articles helpful:
