XM and Sirius satellite radio stations merged today. Each sides' premium channels and talent mostly stayed intact, with stations like Howard Stern, the Grateful Dead Channel and Eminem's Shade 45 all making the jump to XM users, while Sirius listeners acquire Bob Dylan's Theme Time Radio Hour, Tom Petty's Buried Treasure and B.B. King's namesake blues station. Many of the themed genre stations, however, were either axed or assimilated into one station. For instance, Sirius' college rock mainstay Left of Center is done, replaced by XM's similar XMU. The by-the-decades stations are now categorized as "'60s on 6," "'70s on 7," etc. A pair of Rock Daily's favorite Sirius stations, Lithium and First Wave, thankfully managed to survive, while XM's alt-rock trio of stations Fred, Ethel and Lucy learned their satellite days are over.
