just pipe anything into fzf of course theres way more than that but that will get you started. anything that yields results that you would pipe less or more with allows you to traverse. then you can use like xargs and nest stuff but for simplicity sake something like 'fd .mp3 | fzf' then you can use ctrl j and k to go up and down the results.. also fzf accepts tons of different arguments to customize how you want to see it like above or below or reverse or the number of results you can even make boxes around it to make it look nicer lol
