Can I use mobygratis music for commercial purposes?

Yes, but you must apply for and receive a commercial license before using the tracks in monetized or commercial projects. Please note Paragraph 4. In the Terms of Service - “You may use previously unreleased tracks on a de minimus (i.e., very limited) basis where you may be streaming to very small audiences or generating very small amounts of revenue, but if this use grows you must let us know and apply for a commercial license.”
