Project Playlist has cleared the last of its legal hurdles, having settled copyright infringement lawsuits against it by Universal Music Group and Warner Music Group.

As first reported by CNET, and confirmed by Billboard, UMG’s settlement includes a licensing deal similar to that struck between Project Playlist and EMI last year. It’s not yet clear whether WMG will also license its catalog to the service. Project Playlist previously struck licensing deals with Sony Music Entertainment, Sony/ATV Music Publishing and EMI Music Publishing.

"While it was unfortunate that legal action was necessary, we are pleased to have resolved this litigation in an amicable manner,” reads a UMG statement on the matter.

With the legal issues now settled, Project Playlist is clear to offer its online playlisting service to the public. The service never really went away, but just lacked content due to the legal and licensing disputes. The lawsuits were originally brought in late 2008, and shortly after former Facebook executive Owen Van Natta came on board to help steer the service to legitimacy. After his departure for a short-lived tenure at MySpace Music, former MTV co-founder John Sykes took the role and has been guiding the company ever since.

A year ago, it acquired the assets of Total Music, a big move that will allow the company to build playlists off a database of licensed music rather than through the practice of linking to sources of free music on the Internet that got it into legal trouble in the first place.
