Also, I laughed when I read their bit on the money. It was pretty typical "pay if you want... please pay." But then I got to the part where they're donating it all to charity. That's fucking awesome.
What's laughable if they say please pay, but if you don't want to then you don't have to? : ) Even if it's typica, isn't it just ok? (I speak generally, cause in this case I know you state clearly it's different with money for charity). Anyway, that's fine by me, and it is totally worth a tip usually.
And the amount of songs here is insane, I'm sure I'll get to know something new for me.
