Lock Screen Music Player Issues

Question

Here is the deal:
To the best of my knowledge, there is no solution (as of yet).  I am hoping someone can guide me in the event there is.
I carry my iPhone in my front pocket like many people.  I don't carry anything other than the phone in that pocket other than the headphones. Yet somehow, almost daily, the music player starts while the phone is in my pocket.  If I manage to hear it, despite the surrounding noise and whether the headphones are plugged in, I can usually turn it off and save the battery.  However, in many instances, I have pulled my phone out to find that the player has run the battery into the ground.  After doing some general research, I have found that this significant problem is not limited to me.
Now I understand that generally, to activate the music player you have to press the home button twice and then tap play on the music player.  However, day after day the player starts.  I am certain that when the phone goes into the pocket, I press the button on top of the phone placing it in Sleep mode.  Regardless of what I do - nothing seems to work and it is my understanding that there is no setting from Apple to disable the music player.
Therefore, I believe my options are limited to the following and hopefully someone can confirm my understanding or offer better solutions:
1.     I can remove every song from my IPhone.  Without music, there is nothing to play.  Granted it defeats one of the key features of my $600 device;
2.     I can jailbreak the iPhone and rely on the thoughtful functions created by third parties outside of Apple who have thought this process through; or
3.     I can buy a competitive device that is not simply a phone built around a media player.
Frankly, at the end of the day, how is this functionality not a safety hazard?  If I am stranded somewhere with no phone battery because Apple decide not to give me an option to turn off the "lock screen" music player function - I would go so far as argue that this is Apple's own negligence.  A "lock screen" by definition should LOCK THE SCREEN.  This should not be a "lock screen" with certain Apple exceptions.  At the very least, Apple should give the owner the ability to determine whether this information is accessible from the outside screen.
Even worse, assume that I have confidential business memos stored in the music player (this is where it stores them).  What if my phone was found by a competitor who decided to listen to the memo that I have on my phone - based on the current function, there would be nothing to stop them?  Or what if a child finds a phone and the music library contains explicit lyrics.  Is there nothing to stop the child from accessing these.  I cannot believe that the genuses at Apple did not have the foresight to think of these potential issues with the function - therefore, I believe that there must be a solution and I am not seeing it.
Can anyone help?

Answer 1

I do have a passcode - as I mentioned I am using a LOCK SCREEN which is the password protected screen.  My point was that audio memos (like voice memos) are stored as audio files in the music player.  They are accessible through the standard lock screen music controls on the iPhone.  It makes no difference whether you have the screen locked/unlocked.  To the best of my knowledge, there is no setting to turn off those controls which would be the ultimate solution to my problem.
I purposefully don't save such memos becuase I know that anyone can access them.
I am more concerned with the player turning itself on, daily.
