@aba3e4c9 I have a page on my blog about CC music. I used to have good overview of it, but haven't updated it in years. In Swedish, but is goog-translatable, and maybe can be a starting point. I should really check it and update it... 
https://inscius.se/friare-musik/ There is also copyrighted music that is labelled "podsafe", i.e. royalty-free, but I think that is a bit "unsafe", as copyright holders might change their mind.
