IMO, the worst is pausing my media to play an ad in an unrelated application.
No matter what I try, I can't get my music to play over the ad. I can silence the ad, go to my player, hit play to resume the music, and as soon as I flip back to the app playing the ad, the music pauses. So I have three choices: uninstall this shit, listen to silence until the ad is over, or listen to the ad.
I can. It immediately stops itself while the ad rolls. I hit play from the navigation pane, it starts for maybe a second and stops again.
Once the ad stops, I can hit play and it all works normally.
