Judging from the sales of RockBand, you're the only one.
For the most part, Korean/Japanese music brings out the Van Gogh in me.
Also contributing to the drum argument:
Yes, it does teach you on expert to play along with most of those songs. I'm not saying you could get on a drum set and jam out after just playing Rock Band on expert, but the layout of the drums is similar enough to a real set that you could easily play along to the songs you learned from the game. I own Rock Band and I have a neighbor who owns a drum set and is profecient on Guitar...we play the game for a bit and then generally end up at his house - him playing the songs from the game on guitar while I jam along with what I remember of the drum beat.
And yes, I am a fairly involved musician. Music classes make up the majority of my curriculum.
On the other hand, playing Rock Band guitar / Guitar Hero will get you nowhere playing an actual guitar, aside from inspiring you to learn.
