How much extra money has Harmonix gotten out of you from RB?

[madskillz]

$0. However, I want the Halo rock theme from GHIII on RB.

I will admit - after reviewing it, as much as I loved it (and my fam loved it), it's been in its box - extra guitar and all. I think about playing it, but Ashley from Mass Effect keeps calling me 'Skipper ... oh my capitan ...'

Duty calls!
