the singing itch

i have, apparently, started channeling Justice of Toren One Esk in that i'm pretty much constantly singing, and caring less and less about who hears me sing. unfortunately my repertoire of songs is way less impressive, so sometimes i get tired of singing the same ones over and over again. also it can get a bit annoying when i get the urge to sing early in the morning, when i'm still sleepy and my voice is definitely not awake yet and i don't even particularly feel like singing?
