After Time Travel, I Became the Ceiling of the Music World

Traveling through a parallel world, the film and television literature industry is mature, but popular music is extremely barren, with single genres, empty works, and the music scene has been in a long-term slump. The protagonist travels back to a music school student who is on the verge of dropping out and has low self-esteem. With the help of the earth's vast collection of golden songs, professional music theory and arrangement ability, without relying on capital or plug-ins, he gradually improves his singing skills and adapts songs to suit the market. He counterattacks from a grassroots amateur to the king of national songs, and ultimately reshapes the entire music scene.
