On my Denon X4000, yes, there is an easy way... but with conditions.
The music source must be from NETWORK, CD on my remote. It is important to note that my CD source is 2 analog cables from the Bluray/CD player to the Receiver. My BLU-RAY source, from the same Bluray/CD player is HDMI cable to the Receiver.
Bottom line, this method doesn't work if your music source comes to your receiver via HDMI cable.
So if you have a music source that is NOT connected to your receiver via HDMI, try this:
1) Turn your TV on to the proper channel, (thru your AVR normally).
2) Play your music, selecting the appropriate source on your AVR remote.
3) Press OPTION on your AVR remote.
4) Press VIDEO SELECT
5) Turn VIDEO SELECT On - (Source should be showing Cbl/Sat for your TV video).
When you're done, simply repeat and turn VIDEO SELECT Off.
This works for me on an X4000. Can listen to CD or Pandora while watching TV.
