According to your idea will definitely lead to a dead end. No company will use your works, because any company has a complete set of lyrics, music, arrangement and singing, and some stars even have a combination of lyrics, music, arrangement and singing. !

It is recommended that you attack in multiple ways: The first way: 1. Register on websites such as "5sing" and "Composer" and upload your works; 2. Post an advertisement accepting composers and slowly gain fame. The second way: Submit song works to the editorial departments of print media such as "Song" and "Music Life". The third way: go to karaoke halls, dance halls, and bars to contact you about singing arrangements. The fourth way: pay attention to the song collection and competition information of each unit.

Of course, if you don’t know how to sing and write lyrics, it will be much more difficult.
