I think pop artists like Lady Gaga would be more likely to show up in something like this than a plastic guitar-based disc. Repetitive synth lines and drum machine beats would be more interesting switching back and forth between the parts, and playing keyboard parts on "guitar" isn't as jarring when you're just pressing buttons on a regular controller. "Poker Face" and "Just Dance" may have been boring in Rock Band 1/2/3 (aside from vocals), but I look forward to playing them in Blitz.
And "Time of the Season", "Party in the USA", "Have You Ever Seen the Rain?"...
