Classic Rock, period. You'll hear Billy Joel, Boston, CCR, Fleetwood Mac, Led Zeppelin, Lynyrd Skynyrd, John Mellencamp, Queen, Steve Miller Band, The Who, and much more.
Only '60s, '70s, and '80s Classic Rock. Since I unfortunately didn't have the pleasure of living in the era where Rock was at its best (seriously), the songs played are based on what I have heard growing up when my parents were around, as well as some tracks that I consider good enough to be on the station. However, you won't find any '90s Rock on the stations. Honestly, I don't consider it Classic Rock, and I also feel that it isn't up to par when compared to the gems from the '60s and '70s.
