Utility or option to pause music by default (Pause Timer)

Question

Is there no way to make the iPod touch 4 gen automatically pause or stop playing music by default?
It is odd that after all these years, there is still no way to hit the play button and know it will pause/stop playing after a preset number of minutes.
YES I know the iPod Clock app has a "once" timer. Set it to 20 minutes and it can put the iPod to sleep. I'm not looking to sleep the iPod, I'm wanting to pause the music after 20 min. And I want it to do this each time I hit the play button. if I am using an application such as a bed sleeping monitor, sleeping the iPod defeats that application, and others.
I want an automatic function that the pause button of the music player is hit or activated after ~20 min. And I want this repetitive, or persistent or the default option of the player. Not something I have to keep resetting.
I have bought numerous apps to help with this, none of which function to make the music play button pause/stop after 20 min. So that if I wake, and hit the music play button again it will again stop in 20 min. every time, unless the option is switched off.
The apps available are sleep timers, not pause timers and either require resetting each time, or set to a clocked stop time, and/or loading particular song or songs to play (without the usual music player controls).
The most promising application of all, AutoSleep, does not work for me. And even if it did, it cannot run in the background supposedly because of limitations with the accelerometer.
If however, you know how to get AutoSleep to work, and want to help me with this, I'm interested.
If you know a way to accomplish the automatic pausing of the music player after 20 min., each time it is played, I am TOTALLY interested.
I imagine there is no way to alter a function of Apple's music application or clock. (adding a pause instead of sleep to the timer of the clock). Do you know the facts on this last sentence?
If you know of an alternate music player which can run in the background, have access to the library same as Apple's music player, and can be set to a timed "pause" (not sleep) by default (persistently), tell me about it.
If you even know how to help me develop an application (utility - or script) to do this, I have XCode installed and am painfully slowly trying to learn how. I read where others are interested, particularly audiobook listeners, so maybe there's a market for you.
Thanks,

I know that this probably isn't too helpful of an answer, but I know that there's an app for it. I have no idea if it's possible with the default apps, but I bought one off of the app store.
