Better still, you can sync, stream, and cache your entire music library between your Mac and iPhone in full quality. Unlike other services, Loop offers infinite free space and unlimited offline cache. With Loop, all of your music can be stored and is accessible from a cloud. Soundcloud, Last FM and other third-party integration.
