Boston tracks in Rock Band

I plan on doing a full post at some point about Rock Band, but I thought I'd just drop a quick line about the Boston track pack that was just released last week. I picked it up the day it came out and I'm thoroughly impressed. Granted, my love for the music, particularly Rock & Roll Band and Smokin', is most likely due to my unusual and unhealthy love of albums with sweet UFOs on the cover and rockers with awesome facial hair. The note tracking for guitar on hard difficulty is an absolute blast, and I'm excited to jump into the drum tracks, as they sound like they'll be fun as well.
