I am new to Android. Switched to S5. Had iPhone for years. Found this thread helpful because I was having same issues. I recommend getting the Echo Lockscreen app. It pushes your notifications to the lockscreen and makes them much more visible and easier to deal with and they stay until you clear them from the lockscreen or the notification bar. Customizable, but no music control. (first line in the FAQ says its in development)

There is no My Stuff in whatever OS I am using (still don't know how to figure that out). notifications are in bottom left corner of Google screen, not in settings.
