To wrap up Spotify week, I’d like to look at what this new (to U.S. Americans) service provides in the way of social connectivity. Let me first say that I haven’t had the chance to use turntable.fm yet, and I do not mess with Ping for iTunes. From the get go, Ping seemed unlikely to catch on, and I really wasn’t in the mood to join another social network (yet I just signed up for Google + — I don’t understand me either). However, I was excited when I found out from my friend Robbie that with Spotify, you can easily browse and listen to friends’ playlists. Choosing which of your playlists you want to make public is simple, so you can hide that embarrassing one you put on when you’re a sad, pathetic mess WHAT I’M NOT TALKING ABOUT MYSELF… or, if you’re extremely proud of one, like a certain someone — Spotify account name YouHearThat — is of their Mario Kart playlist, you can make it available for all to see. This special list of upbeat songs has been battle tested and is guaranteed to boost your Mario Kart performance (trust me on the John Williams stuff — you haven’t lived until you’ve won a race while blasting the main theme to Star Wars). One of my favorite tunes on the list is Karmin’s cover of Nicki Minaj’s “Super Bass.” While Karmin is usually a duo, this cover features ?uestlove and Owen Biddle of the Roots, and I’m not sure if it’s the driving synth percussion on the chorus or hearing BOOMBADOOMBOOMBOOMBADOOMBOOM repeatedly, but this tune never fails to send me on a red-shell-slingin’, banana-peel-droppin’ rampage. Check out the video above and download the song from iTunes here.
