Great post bro. I will try your technique but I fear that I'll have to try it a fewer more times again and again and again.

In addition, One may have to remember that our world is run basically by principles and Laws. It's our duty to be either ignorant of this fact or knowledgeable about it and use it to our advantage.

Two of these laws is

1. The Law of Displacement
2. Nature abhors Vacuum

The law of displacement states that a law will continue to exist if a superior law doesn't come into play or into the scene.

In other words, the effect of a smaller law is annuled once a bigger Law/authority/Principle comes into the scene.

The song gets into your head in the first place through your auditory gates, your ears. And somehow is replaying because of another Law

In addition, one has to be aware of the fact that There has to be a song always on or in your mind's playlist. It can either be paused or tuned down per time depending on one's dominant
activity

Garbage in, Garbage out.

All one needs to do is to look for another law that is higher than whatever laws are playing at the moment. And the Principle of displacement of a lower law by a higher one wins

In this case,

1. Look for your favourite songs that spur you up emotionally and connects to your soul and spirit and plug it into your system through your ear gates either with A very good ear bud or Headphone.
2. leave the songs on repeat with a high volume.

After sometime, you will find out that the right songs that get you going and more productive are what remains in your system.
