Check out this website
https://www.tunefind.com/show/andi-mack/season-1

It features some songs that were heard and identified in Andi Mack.

Plus the website, Extreme Music, is a music library that features tracks from the show too.
Use Tunefind and search for the tracks on Extreme Music. I found Dancing in the Dark on there.
