I learned long ago that a song is worth two prayers(thoughts). I’ve been singing from my heart ever since (had to my voice is only good in a choir). I’m a member of this group:

They teach how this is done. I found this through Gregg Braden and have read his books the “Isaiah Effect” and “The God Code” to name a couple of his inspired works. So if you want to learn to sing with your heart. This could be the place to do it.
In Peace and Unity,

PS: Thanks,mudra, for sharing that song it brought tears to my eyes.
