For Spotify users, you can add the currently playing song name displayed on the top panel in Ubuntu 20.04 via Gnome Extension.

There’s a Gnome Shell Extension called ‘Spotify Song Label’, which adds the current playing song as well as artist in the top bar.

It can be placed in the left, center, or right of the top panel, with options to change left / right padding. And it has ability to toggle between Spotify window and last focused app.

How to Install Spotify Song label Extension:

1.) Firstly make sure chrome-gnome-shell package is installed. And for the configuration tool (see the previous picture), install the gnome-shell-extension-prefs package:

sudo apt install chrome-gnome-shell gnome-shell-extension-prefs

2.) Go to the extension web page and turn on the toggle icon to install it.

Don’t see the toggle icon? Click the link which says “Click here to install browser extension” to install browser extension and refresh the web page.

That’s it. To change the extension settings, use either Gnome Tweaks or Extensions you installed via step 1.
