Funeral personal song

I've arranged for a song writer to start creating with me while I'm well enough to say all I want to say after I pass away we've looked through and it'll cost a lot more than I can manage myself. I'm 30 and have been through a very unhappy life but music it's like my soulmate I use it to feel to block out and to be happier everyday. All my loved ones know the importance music is on my life so to gift them a song to play to cheer them up and be able to play whenever they want it's something special my last gift to them.
