Yep, so the leak is good.  Looks like there's yet another leak, so expect that to match up next week as well.  I'm getting Freeze Frame, and maybe American Band.

Freeze Frame was my favorite song as a 4 year old. So yeah, I might buy it.

That is a good set of songs.

I picked up the two Grand Funk Railroad songs and that's it.  Have exactly enough for a three pack and I don't want spare points I can't spend on anything.  Stupid Microsoft funny money.

I just ranked #9 on Loco-Motion! WOOHOO! It's probably going to last all of three seconds, though...

I saw the asterisks and for a second was like "wait, is Rock Band going back to covers?".
