Can I use UT3 music for a Marketplace item trailer?

I’m working on a UE4 code plugin that will be sold on the Unreal Marketplace and only on the Marketplace. Right now I’m working on a trailer video for it. I was temporarily using the song Sanctuary from the UT3 soundtrack and my plan was to replace the song later. However, I’m quite happy with how the trailer is currently so I would like to ask Epic whether it would be okay to use this song, seeing as UT3 is your property and any profit resulting from the trailer will benefit Epic as well.

This is approved

Thank you!
