That little humming inside my head

I love singing and I have it in my blood, it's a rush that elevates me so high in the lows and higher, I sing without knowing, everywhere, outside I have earbuds or headphones on and I can't help it, I've been singing most of my life; I might have found a way to record my voice on music on my phone, a third party app that allows the music player while recording, and maybe that David Gray song that I can't stop hearing even when I quit playing the tune. We'll see.
