I know from this thread that a lot of you haven't really explored the Rock Band Network. So I'm taking it upon myself to step out of the RBN ghetto, get in your collective faces a moment, and introduce myself. I'm James, and I make music. There's a lot of it up on my website, The James Rocket, for free.
I've got two songs in the Rock Band Network, Paper Valentines and Shiny Dark Bar.
Granted, they're both RBN1: charted back in the olden days before there were any such things as newfangled pro guitar, bass and keys. Happily, though, Paper Valentines plays pretty on RB3, and is pro-drum friendly. AND IT'S CHEAP. And look, I'm even giving away a free mp3 right here. Wasn't that easy? If that ain't service, I don't know what is.
(Sorry to the PS3 folks. They don't port over the old stuff anymore...)
