Pocket Hipster is some new app you can download on you iPhone, iPad, iPod Touch, etc..., I just read about that allows you to send music into a virtual "hipster" who critiques your current library of music and then reccommends a grip of cool new music to you. The article I checked out is at PR Newswire.
Two companies, The Echo Nest and We Are Hunted, teamed up to make this new app available which is pretty cool. Definitely check out those two companies sites, they are fun to play around with and have tons of music and apps to download if interested. Actually those two websites are a good way to explore music and find something new without the app they created.
So this is pretty cool for everyone who is looking for new music or just more of the same music. I do not know exactly how they get their music other than what they call data mining but it seems like they are doing a descent job.
