Rock Band DLC - PAX Pack

Well, after last week's troubles with Rush there were some concerns, but that delay aside, there IS new Rock Band DLC this week. The PAX Charity Pack! That's right, Harmonix is donating their proceeds from this pack to Child's Play, the Penny-Arcade founded children's charity.
The songs included in this pack are a classic from Jonathon Coulton, the Achewood theme song, and the Lovecraftian 'The Darkest of the Hillside Thickets'.
- Jonathan Coulton - Skullcrusher Mountain
- MC Frontalot - Livin' at the Corner of Dude and Catastrophe
- The Darkest of the Hillside Thickets - Shhh...
Tracks will be (are) out on Tuesday on Xbox Marketplace and Thursday on the Playstation Store. The whole pack is $2.99 (240 Microsoft Points), or you can buy the individual tracks for $.99 (80 Microsoft Points). If this is being donated to charity though, why are they discount price?








I am not really familiar with any of these songs but I plan on buying the pack because the $$$ is going to charity.
