As I’ve mentioned before, one of Android’s biggest areas for improvement is in the handling of on-device music.

One of the apps trying to fill that void is moodagent, which has been available on iOS for some time now, but is now also available on Android.

moodagent automatically determines various characteristics to your songs and “profiles” your music. Think of this as a variation to a song’s genre, but whereas a song can only have one genre, it can have several “moods”.

moodagent takes “emotion, mood, genre, sub-genre, style, tempo, beat, vocals, instruments, and production features” into consideration when creating its playlists. But the really cool feature is it’s “mood”-based auto-playlist generation. That’s a mouthful, but in a nutshell, you’re given 5 sliders to adjust up and down. Modifying these will give you a custom playlist and start playing the top song immediately.

moodagent is “socially connected” as well — a feature that lots of apps are getting these days, and that I don’t much care for. You can post your current playlist to either Twitter or Facebook. I’d show you what the Twitter screengrab looked like, but it was just a page full of error messages (this could have been a Twitter error — I gave up after several tries). Here’s the Facebook screengrab:

It’s a novel approach to music, that’s for sure. Still a little lacking in the UI department (in the app you have the playlist view, and there is no widget), but it does what it’s supposed to, and it is an improvement over the stock Music app.

moodagent is free in the Market and is subsidized by ads.
