Moodagent is one of those apps that seems like, at first glance, it’ll cure world hunger, or abruptly manifest all those single socks you’ve lost over the past seven years — a holy-crap,-I-just-gotta-have-this-app, app.
What it promises to do is create a custom playlist, culled from your collection, based on five settable criteria: sensuality, tenderness, joy, aggressiveness and tempo. Unfortunately, my pet chameleon could have created a more cohesive playlist (had I an actual pet chameleon — which I don’t, and had I days to spend waiting agonizingly while he crafted my custom playlist — which I also don’t).
As an example, in the screenshot above to the right, I’ve pushed three criteria to the max: tempo (extreme right), aggressiveness (middle) and joy (left); under the bars are the top-five songs of the quickly whipped-up playlist. Now, neither Tool’s “Sober” nor The Police’s “Synchronicity II” could, by any stretch of the imagination, be considered joyful; but even more horrible is that any playlist including both Tool and Kelly Clarkson within a few songs of each other could quite conceivably create a rift in the very fabric of space-time.
But it’s free. So check it out, may work for you.
