I had this happen a few times now. I use my plantronics voyager pro on my ride home. I power it off when I get home, and it seems to launch the Sirius xm app. Has anyone noticed anything odd like this themselves?
I don't have these apps, so this doesn't happen to me, but my phone seems to like to start song at a random part of the track instead of the beginning from time to time. It's pretty annoying. I might try a restore and see what happens :/
