Once you join the IMLC, we will be asking for your music to sell to our clients - as much of it as you feel comfortable sharing. The first step to a successful music licensing career is a healthy and diverse catalogue of royalty-free music. Keep feeding it and it will keep growing!
The IMLC is a royalty free site. We therefore do not accept tracks that are registered with a PRO, collection agencies, such as PRS. Keeping your music royalty free enables you to take advantage of the ever increasing royalty-free music market by selling non exclusive licenses with companies like the IMLC.
As long as you've created your music independently and own the copyright, then they are no limits to what you can achieve by making it available via the IMLC.
