I’ve always been impressed with how Spotify has not only changed the music industry, but it’s changed mobile music apps at the same time. One of the things that sets Spotify apart from other music apps is the fact that they include a social aspect to it. Your friends on Facebook can see what you’re listening to. This was controversial when it first came out, and I was hesitant to jump on board with it also, but ultimately I’ve found some great music because (I may be biased, but) my friends have great taste in music. For students, $5 a month can get you unlimited access to mobile streaming. Spotify organizes its music on the mobile app wonderfully, separating its music into categories, moods, and activities. My favorite part of Spotify’s mobile app is that it learns about the user’s taste in music. Using these observations, Spotify creates a customized playlist just for you. This falls into good mobile app design because of two reasons: first, it knows its audience, and second, it adds an extra layer of polish (remember, the money is in the details). Other music companies are seeing the success of Spotify and their mobile app, and are jumping on the bandwagon. YouTube is now allowing offline streaming for a premium price. While it’s not as good as Spotify yet, it’s getting there. The only reason that I bought a premium Spotify account is because I thought it catered to millennials in college (who can beat $5 a month?) and all my friends were talking about how great it was. They had such a strong fan base, that I was convinced.
