How can we Develop APP Like YMusic?

Hello Everyone, I am not a developer so want to answer this question. I want to create my own app like YMusic and also like Spotify, and Pi Music. But, developer charge $50000 for this type of app. Its very huge amount for me. So, anyone can help me to create this app or if you are a developer then please suggest me and share your offer.
