I subscribe to both Dish and Sirius. This week they are announcing on the Sirius channels that you can now listen to their music streams on Dish, and sure enough they are there. Have a look starting at channel 6000 and you will see about 60 new channels of music. Interestingly enough, the old music is still there too.
There is a music guide on Dish's site.
