@MusicFanInSC Genre stations such as your 2000s Country Station will primarily play songs from the 2000s, but we will also play an occasional song from other eras to provide a more diverse listening experience. You can use Thumbs Up and Thumbs Down to tune your station to your liking and let us know what you want to hear more or less of.
You can also use Pandora Modes to customize your station experience when you're listening from a computer, mobile device or the Sonos app
Hope this helps explain.
