Are all the songs on the Jukebox copyright free?

Hello!

I'm currently making a video on the new season and in the video we listen to songs on the jukebox as always, But I wanted to extend one of the songs out for more of the video so I went searching for it, expecting to be part of the DRG soundtrack.

To my suprise it seems like most songs on the jukebox are actually from various music libraries and many of them appear to copyright free, but it was hard to tell if that is the case for all of them or not.

In this instance the song 'Psychedelic Surfer' by Rob Johnson, I couldn't find anywhere if it was free to use or not.

I found a thread on here from 5 years ago that seems to imply all the songs are either copyright free or at least owned by gsg in some way but considering how many years it's been, I'm wondering if that's still the case?

Tl;dr: Can I use any song from the jukebox for my videos on DRG?
