What does royalty free mean?

Can I use this song for free? (Only for non-monetized or non-commercial projects)

You can use this track for free in non-monetized and non-commercial projects. This track is registered to the content-ID system Adrev. If you use it in your work Adrev's content-ID tracking system will detect your video using my music and give you a third party copyright match notification.
This is only a notification. Your video won't be taken down nor will your channel get flagged. Adrev will only monetize it by placing short ads in front of it and generate ad revenue for me. This way you don't have to spend money but I can still receive payment by advertisments and treat this channel as the job it is.
To assure everything proceeds without problems please comply with these three conditions:

1. The work in which this track is used must be non-commercial (no monetizing or gaining money in any other form).

2. You must give credit to me by mentioning my contact information in your description:

Aggressor (Ft. Lara Ausensi)

Starting my own film and production company...Looking for hot blazing music for my film and series projects...Hopefully bigger and better things will allow me to continue relationships with the artist I meet on sound cloud....Like Lou Sir the third and Volkoff Beats and I can't ever forget the neo soul sound of Stephon Evans
