What is a smart way to fill up white space on a profile page (audio streaming platform)

I have a pretty simple profile page on my website which already contains some elements: the banner, profile picture, about section, timeline, suggested users panel and some various other little things. However, there is a fairly large unwanted white space (roughly 200 pixels) on the left side of the timeline.

Unfortunately, I don't know how to fill up this space as most of what's available (as far as posts and user info go) is already placed on the page. Someone suggested adding a user gallery, and although it's somewhat a good idea, the website is an audio streaming platform - not an image sharing one.

What are some suggestions? Every idea is welcome :)
