Dear brother/ sister Intercore,
You are correct in that you created this version only, but when planting a garden, do you take credit or give it to Jehovah? You didn't create the seeds, just like you didn't create the figurative "seed" of this song that you put out.
Additionally, what if your "karaoke" version were to get in the hands of apostates and they gave you credit? They might make new lyrics or make fun of the fact that songs like "just around the corner" are things that have been said for many generations now without coming true. It could bring reproach on your name, and Jehovah's as well.
It sounds like Satan is playing the instrument of your heart, dear brother. You should do some deep study, meditate, and hope that you can root out any of Satan's seeds that are planted in the garden of your heart.
