FYI... Samsung has snuck another ad in. This one is in the clock app, under alarms. When you create an alarm, everything looks good until you go to add a sound... Where normally it would take you to your mp3s, now it takes you to an initial choice where you can select to go to your sounds, or an option/ad to install spotify.
The Google clock app has pandora, YouTube music, calm and Spotify. But it only requests once before its hidden away.
