Music can aid the concentration or it can be a big distraction. Vocal music tempts me to listen to the words instead of getting on with what I'm meant to be writing, whereas heavy metal's great for doing the housework to. But what to choose while continuing to key in rewrites? How about these guys -

I don't think the Iyessi could come up with anything more suited to the task. That said, here's another Iyessi song:
In the night, in her dreams
Little Valer-relo walked.
Nightmares lurked in tangled leaves
Just beyond hearing.
In her path there sat a soldier:
"I will slay the beasts for you!"
Off the path, in the thickets
The faithful soldier leapt.
When she woke, when she rose
Little Valer-relo found
His sword was in her hand.
