To add lyrics, you can use a visual composer widget called "Accordeons".

First, make sure Visual Composer is enabled for custom post types such as Albums and Events. Go to Visual Composer setting and enabled it for "Album" and "Event". See screenshot:

Once activated, go to Discography > All Albums and edit the album of your choice. Click Back-End editor:

*If you don't see this button, it means that Visual Composer is either not activated or installed, or it's not enabled for your discography (see first step).

Click ADD ELEMENT then choose the Accordeons widget. See screencast:
