Hi MonnoDB!
I listened to the song yesterday no my laptop, but the speakers are busted so I paused it. It might be the early morning, coming in from a smoke and coffee, freezing outside, I put on my good headphones and listened two times in a row. A warm embrace.
The song is quite simple, but the performance is nothing but simple. Moving to say the least. In a way it saddens me, breaks me down. But it's worth all that pain.
Have you tried playing/singing it a whole note lower? Your voice sounds just a little bit airy to me.
Thank you for this song,
Martin
