Underlying music for Drone videos

[AnGo]

Hi. Question to those of you who are recording drone videos probably to publish on public platforms like youtube. I think it's a common thing that such videos are edited with underlying music to prevent silent or propeller-sounded videos. Where are you getting your music from? Is there any source of suitable good "free-to-use" audio tracks that can be published without having issues with intellectual property of any artists, other law stuff etc?
I already noticed this thread here:

Sharing My Music and Sound Effects - Over 2000 Tracks

Hi everyone, I've created over 2000 tracks of music and sound effects that you are welcome to freely use in your videos. All I ask is to be attributed as stated on my homepage: Soundimage.org I'm a big fan of drone videos so it's always a treat to hear my music in them. I sincerely hope that...

But beyond that, what are others maybe using/doing?

I actually make my own music and add it to my drone videos.

I edit with Wevideo, it has music in it available to use. If you edit with YouTube it also has tracks to use.

Search the type of background music you want e.g. Suspense or Joyful etc on YouTube. Click the 'Filter' on the result page then click on 'Creative Commons'.
