Rock Band got Better?

For those of you completely out of the loop, Rock Band had an update recently that made it even better. It makes the talking sections of singing easier to accomplish and it's now much easier to perform at all of the venues in Band World Tour. But the part that excited me the most is the addition of the Rock Band store. It had been possible to download songs for the game before, but it was fairly annoying. Now you can preview a song before buying it and it's all but eliminated double purchases. Way to go Harmonix!
