Need clarification of licenses Envato Element Music


As as new and usual always struggle. I am Envato Element subscriber.
Just got a small part-time job to create a small video ads for FB for their fancy wedding rings business.

They have a lot of ring designs.
So my question is can I use same music to same company project but different rings ?

Or should I need to create an individual project with an individual ring ?
If this is a case, I mean if they like to use one music in 100 video with different design, would need to create 100 license/projects.
I do not know how many project can attached with one music.

Need little help here !


IMHO one ring = one end product = one project.

Unless you will make it as a consistent series. Series can be treated as a one project.
