There is no one-size-fits-all answer to this question, as the best way for an originator to have control over their original lyrics, beats, melodies, etc., for commercial use largely depends on the individual's country and its relevant copyright laws. Generally speaking, however, the best way to protect an original work is to register it with a performing rights organization such as ASCAP, BMI, or SESAC. These organizations collect royalties from those who use copyrighted works, allowing the originator to be compensated for their creations. Additionally, depending on the country, the originator may also need to register their work with the relevant copyright office, or file a copyright lawsuit in order to receive full protection.
