For adding songs to your phone, you'll need to check your phone's manual... to see whether you can only add songs with certain extensions (eg .mp3) & also to see whether you need to add songs to a certain player before they'll transfer to your phone.
For example, I need to add files to WMP before I can transfer them to my phone.
