Seems like I'm that "one guy" who voted for GDRB
Beatles: Rock Band
Green Day: Rock Band
LEGO Rock Band
Rock Band Unplugged
Rock Band Blitz
Rock Band Mobile
Rock Band iOS
Rock Band Reloaded
That one puzzle game they had on Facebook that was like a combination of Collapse and Bejeweled
this is a hard choice between Blitz, LEGO or The Beatles
but my vote will got to Blitz
"Fire has other worldly powers" -Lawdog1521
Yep, going for Blitz as well considering it is the one I find myself keep playing and coming back to even after importing the tracks to RB3. Beatles and Lego comes close behind (surprise, surprise)
The Beatles by far. The whole game is a love letter to the band. It really immerses you in their whole career.
800 Tracks: RB + RB2 + LRB + AC/DC + GDRB + Blitz + 22 RBN + 448 DLC
My Rock Band 4 Ultimate Setlist:
I don't know if the last one is a real thing or not but I voted for it.
I would have to say Blitz though.
 Katy Perry
 Dream Theater
No question - The Beatles Rock Band

Lego by faaaaaaaaaaaaaaaaaaaaaaaaaaaar.
Has the best setlist of any Rock Band game outside of 3, has one of the most amazing art styles in any game ever, and has setpieces that made me drop the controller down and say wow, which no other game this console generation has ever done.

Lego was amazing.
Birds of Tokyo
We Are Scientists
Art Vs. Science
Green Day. Not because it's the best setlist or anything, but because damn, full motion capture. It's really nice.

RockBandRocker: We will all migrate to the Dance Central forums. It will be like Moses leading the Israelites out of Egypt.
Munnchy: Only Flashier, with impeccable dance moves.
RockBandRocker: With more glitter and glam. We will survive
