Come on already!!! No adult R&B music from late 70s and 80s on Sirius??? 22 rock channels, but no R&B (non hip hop) from artists like Gap Band, Roger & Zapp, Con Funk Shunn, Cameo, Earth Wind & Fire, Rick James, what gives? Its on XM's Groove- why not Sirius?? It is slap in the face to a certain ethnic & demo group for sure.
