Using the same license for multiple videos

Hello everyone!

I am currently thinking about starting a channel for commercial use. Right now my budget is very very limited and I can only really afford to buy a standard license for the Audio that I have chosen. (It is very cheap already and even if I go with cheaper options I wouldn’t be able to afford enough licenses to create more than 10 videos.)

Now my question is:
All of my videos are pretty much about the same thing. Will putting these videos into a playlist of 52 videos be enough to count as a series? All of the videos will be released within less than a year. They are also about the same topic on the same channel (product reviews and tests). Would that work out or is there any other way to make it possible to use the music without buying dozens of licenses, that I sadly cannot afford at the moment.

Thanks for your help!
