I made a song with visualization

Now I want to dominate to world for my overlord the supreme cat.

Well, i didn't understand the concept of this song, maybe is it a particular kind of music that i don't know but this song seemed pretty random to my ears. I'm not here to say "it was crap" but i'll say it was not to my taste. Maybe could you explain me?
Btw, if you're a beginner, maybe follow some tutorials or doc online to help you improve your skills.
Ps: i'm not a native english speaker, hope i didn't seem aggressive.
