How to Standardize Genres in Music App on Mac?

Hi!

I am going through my library and want to try standardizing by Genre. For example, I have songs listed under one artist using the below Genres, when I want the artist to only be under Hip-Hop

• Hip-Hop
• Hip-hop
• Hip-Hop/Rap

Is there a way to do a find and replace (Ex: I want to use just Hip-Hop, can I find all the songs under Hip-Hop/Rap and mass change the Genre) for fields in Music en mass? Perhaps a macro that would do this automatically
