One License for each Project ... What is a Project?

What I mean … is a Youtube Channel a Project or is a single Youtube Video a Project?

A YouTube video is a project. Or a series of YouTube videos can be considered a single project if the licensed music is used in the same way in every video in the series - such as using the same music as an intro track, for example. You can use the same track in such a way for a maximum of 52 videos over one year with a single license.

I think I understand … thank you
