The benefits of being able to write in bed are surely great. Had about four hours of U2 on shuffle....some good stuff I haven't heard in ages and now just a random selection. Currently Streets of Love by the Stones.
I've been singing a bit, I feel like I'm getting pretty good at adding rasp in a good way. The way that doesn't hurt your vocal cords, and enables you to just switch to a clean voice.
Rasp is quite difficult, I don't know how people do it so well. I've been learning to sing with a lesser vocal capability because of my throat - but working back up. Can't do falsetto any more sadly or my screaming.
It's important to take care of the voice. I haven't sung enough in head voice, can't do the "I'll give your roses..." extra ZooTV verse on MW that good anymore.
