I really love using Spotify the free service (with options to upgrade to a premium service) that lets you discover and share music.
Pay Attention to Discovering and Sharing as a PR Strategy
I am spending more and more time helping clients discovering new voice to reach out to, share their technology and insights with, and connect with new enterprise and consumer end users by relaying content through their networks.
Yes, I still do very traditional, old school PR, but if you take a moment and see what Spotify has done, and how it impact your own music selection and discovery behavior, maybe there is something you can learn in your media, analyst and blogger initiatives.
Make your content compelling so it can be discovered and of course, shared.
