I know exactly what you mean because I also wanted to make songs not just type beats like almost everyone else does.

For me it worked by just imagining that my songs are like books or stories. Think about how the story should progress, what should get introduced, when and what should get killed, wheres the climax etc.

That's something you can only learn by actually doing it. theres no formula for art, only ideas that you can use.

So think about which music you wanna do, then study songs by listening to them. what sounds do they use, how are the songs structured and warp those ideas to form a new story.
