This reddit is for freely-distributable music. Artists who want their material to be shared and enjoyed. Nothing pay here.
Suck it commercial monopolistic radio networks. Independent artists are doing their own distribution and the Internet is the new radio network.
Please stop reporting YouTube based submissions for not being downloadable. If you Google, 'How to download audio from YouTube' you will find a bunch of different plugins and web-based services that can extract audio from videos.

If you need to add copyright free music to your videos the best tool ive found is Aimi Sync https://link.aimi.fm/Sync
You simply upload your video and they will analyse it and add music to it. You can control the instruments, genere, tempo, etc. You can also add voice overs in many different languages.
And if you are a live streaming, you can use their live streaming tool to play copyright free music during your live stream: aimi.fm
