Long, royalty-free calming piano music needed

[Natural Studio]

I'm looking for royalty-free relaxed piano music. I tried to search for it, most of them are royalty-free indeed, but cannot be used in Youtube videos because of the Youtube's Content ID system. I'd like to use them is relaxing videos, for example:

I know, there is an audio library in Youtube, but it contains mostly shorter musics.
Any advice?
Thanks
