Alphabetic search bar

I’d like to be able to sort all my posts in alphabetical order. Each post is a song with lyrics, audio and other links to listen to or watch Michael Jackson’s music. I’d like to add an alphabetical search bar to my website, either to the side bar or on top of each page.

I cannot find a plugin or a widget that will add an alphabetical list to my website.

My website is https://mjlyricsonly.com/.

Thanks for any suggestion.
