I do miss MySXM, (and my Lynx) but these channels (the new 100+xtra) are nice lately. I've used them at work for a good mix up from the regular genres and the playlists are curated enough to make it enjoyable for everyone. the workout and 90's/2000s party stations were good background for everyone. I wish radios got more of these, but on the app its great, which is where most of my listening takes place these days anyways.
However, my internet is down right now and can only leech internet here and there until next week, which means I busted out the old stiletto and antenna and plugged that bad boy in again. Good old "offline" sat radio.
