The 890 has a Media button, so you can also use the "Favorite Channels" feature. The "Favorite Channels" feature is also available under the "Listen To Music > Listen to Satellite (Listen to music channels broadcast by satellite or digital cable)" activity type. This activity type does not require a display device and is the one I use to listen to my PVR (SA8300HD) digital cable Music Channels.

Note: With the website interface, the "Set Up Favorite Channels" option is added next to the activity, but with the Client Software interface, the "Favorite Channels" setup is under Activity > Settings > Set Up Favorite Channels.
