How do commercial rights actually work?

[elliswill]

I feel like I've searched the entire internet, and I still can't find a concrete answer. Maybe it simply doesn't exist. If I want to offer music creation services, and allow them to use the song for projects which they may or may not profit off, am I able to do so whilst still owning that song and able to do as I please with it? Does ticking the commercial use box mean they can claim they made this song? I want them to be able to use the song for their film/video, but I don't want to lose any rights to use that song however I want at any point in the future, given I made it. Lastly, is Fiverr's commercial use option talking about the sale of the master file, or the entire idea and everything surrounding it?

Some info is on the terms of service page: https://www.fiverr.com/terms_of_service

I'd look at the ownership section in that TOS and the other sections below it.
