As if announcing Rock Band 3 weren’t enough to make me work on vacation, Harmonix also unleashed this bombshell this afternoon: Next week will see the debut of four Lady Gaga tunes in Rock Band. Yes, that Lady Gaga.

“Lady Gaga Pack 01” will include “Bad Romance,” “Just Dance,” “Monster” and “Poker Face” — but that’s not all. Also releasing next week will be the Cartman-fronted, South Park-special edition of “Poker Face” that I mentioned a couple Fridays ago.

This is just one of many examples of how awesome Rock Band is.

Anyway, the songs appear to hit next week at usual times, and for the usual $2 apiece, with the whole four-pack going for $6.99 (or 560 Microsoft Points). I’ll have my traditional links and samples for you later this week…but right now, man, I’ve got dinner plans. Have yourselves a lovely evening, because I sure will.
