App that can search and play any song on command?

I heard of an app called GhostTown that could find and play any song you searched as long as it was on YouTube, but all of the sites that I read this from are from 2011 and I can't find this app in the app store.

Is there any other app that serves the same purpose?

If you want to search for songs on YouTube, why not just use the standard YouTube app?

YouTube doesn't continue playing audio when you're not in the app like music apps do.

You're right, it does stop playing when you leave the app. I'm going to have to investigate if there's a way to do it in my app. That would be a useful feature.
