I'm looking to use string split to access comma separated data in this vue 3 array using checkbox filtering but I can't work it out

I have an array of data and I have checkboxes to filter the array. The search section works fine but when I try to select the filters, none of them work due to the data being a comma separated string.

Here is a link to the codesandbox where you can find the code: MusicView Link

Here is the page: Music Page

This is something that I am struggling to work out and any help would be great!
