Depends... I listen to the Sirius XM app daily and it's a mixed bag. I like to keep it on Howard100 and when I get in the car after being away for a few hours (and listening to nothing else on the phone in that time) When I get back in the car one of the following happens with about equal probability:
- Howard 100 starts again with the live stream
- Howard 100 starts from where it was when I got out of the car
- Random podcast from my podcast app starts playing
- Random Apple Music song starts playing
- Nothing - I have to pull phone out and start the SXM app
As for the app dropping out/freezing, that doesn't really happen to me. I had an issue once or twice where audio drops out, but it still looks like everything is "playing" fine. If I pause/unpause that usually brings it back. Sometimes I have to unlock my phone and pause/unpause from there.
I so wish they had a SXM app for the car. Once they start charging the annual fee for the premium connectivity, I hope they make some changes to make it worth it.
