yes i can reply to that,sirius business radio has 65 music channels available,and as well,if you would want to,you could listen to the talk channels in your business,the reason i know this is that i have been a authorized SIRIUS RADIO DEALER sense early 2003 for residential and commercial establishments,i have installed sirius in many Mexican restaurants other types of business's.
unless they have changed this policy recently,which i don't think they have,a business can listen to what ever channel on sirius they want to.
the music on sirius and xm are pretty similar,but just from experience i believe sirius is easier to work with as far as business goes,and it is still 3 dollars a month less expensive.
