Sorry if this was posted. I am brand new and a quick search didn't come up with a result.
I'm interested in advanced search options. Specifically, I want to be able to filter by recordings/finale files and by [creative commons] license (e.g. as I want to use some of this music for small-time "commercial" projects, (as well as by the more usual criteria like composer or genre or instrument) I need the appropriate license. Is there anyway to filter through all of the data this way?
