Yes, your loved ones who have passed will speak to you through songs.  They will get your attention through those lyrics, and it is quite easy for them to do so, for they are patterns of Consciousness — Spirit in expression — just as you are.  To send you the important message, “I am here, I live on” they use their Consciousness to snag your Consciousness.  “Listen now to the radio.  Turn on this station or that.  Notice what is playing now.”  They are as aware of what you are listening to as you are, for they are with you.  How could they not be?  You all share the same Divine Mind, albeit in different forms.  We will continue with our messages using whatever stories necessary until you understand that you are as Divine as your neighbor and love never dies.
