Before you go buy a Xbox 360 for the DLC (if you do) it is worth noticing the XNA have some pretty big country limitations, so if you don't live within one of the countries with XNA enabled you might be better off getting a PS3 after all.
Wish there was a way to help without having to buy that $99 subscription fee.
Are you part of RBN? We have some minor pipeline issues to fix that have prevented the release of 3 songs, but to get more tracks the RBN needs an active community of authors and peer reviewers. I'm still approving songs and reviewing new submissions, and there's a decent amount of content in the pipeline, but the key component of any UGC initiative is the users. If you'd like to see more content, or more of a specific kind of content, get involved, and help make it happen.
I for one am trying to become part of the RBN, but my emails to support keep disappearing into the ether!
It's all right. Everything will work out fine.
It's all right. We're going to the end of the line!
