Each service offers channels related to specific decades. In your opinion which services does the better job? it would be helpful if you also posted your reasoning. :
Wow. XM is off to an early lead. I prefer the XM format here but not overwhelmingly. It is pretty close. it isa t least partially a reaction to some of the "streeam jockeys" at Sirius. But I realize that this is pretty subjective.
With the exception of Sirius 9, the Pulse, XM wins out for the decades. XM has Flight 26 "Modern Music" but it doesn't have quite the variety that Sirius 9 does.
