No more Sirius (in a roundabout way)

I cancelled my Sirius. Yep, Dave the biggest supporter of Sirius cancelled his Sirius. I then went to the store and bought an XPressR and signed up for XM. I got XM and the best of Sirius package for 16 bucks a month. The way I see it, I only listened to Stern and Soccer, but I'm gaining baseball and hockey which is fine with me. I'll miss the Metropolitan Opera Channel, but I'm sure that XM has a suitable alternative. The Best of Sirius includes Howard and Football and that's about all I was interested in. I don't care for NASCAR, Playboy Radio, or Martha Stewart. I thought about doing the best of XM on my Sirus account, but it didn't include baseball or hockey. I'm happy with my decision, and will be even happier when Sirius refunds my money. For those with XM, what are the must listen to channels? I've already preset Howard 100, Howard 101,Opie and Anthony, MLB Home Plate, NHL Center Ice, and the Presidential Channel, as well as XM's NPR channel.
