Since launching on Spotify last year, Moodagent has been one of the most interesting apps on the platform. That’s because it takes standard algorithmic music recommendations and beefs them up with emotional intelligence.

There are at least a dozen apps that let you build a playlist based on related artists, but Moodagent factors in the mood of each song to build out something that feels more consistent. The options look broad, but are surprisingly powerful. A playlist can be sensual, angry, happy, tender or some combination of all four. You can even base them on tempo, playing back a series of similarly paced songs. Tie these characteristics to the same kind of artist-to-artist matching algorithm that fuels so many other music-discovery apps, and you have a uniquely intelligent system for finding new music.

Wonderful app. Can’t express my gratitude in words.

One of the best music apps available, creates well balanced playlists and the sliders allow good flexibility, general music profiling is good but do be prepared to sync with computer profiler to get all tracks profiled

Took a few hours to analyze my 20,000 tracks but seconds to seamlessly create a playlist segueing from Betty Carter to Edu Lobo via Segovia and Betjeman. Works brilliantly at higher tempos and different moods too. Looking forward to many hours rediscovering my music.

Now I don’t have to worry to choose which song I wanna hear. Just set up my mood profile and tada… It’s magical!! I can rely upon moodagent to choose the best tracks for me. Never let me down. Would love to give 10 stars out of 5 if been allowed.

Moodagent is a must-have for anyone with music on their iPhone… like Pandora, but using your own music. Don’t know what you want to listen to? Just set your current mood on the sliders and Moodagent instantly kicks off a playlist tailored to your mood. The funny thing is, I frequently find myself discovering songs I didn’t even know I had. I guess that’s what happens when you have thousands – some just slip through the cracks. Just buy it, I promise you wont regret it.

I saw an article about this app on Twitter. I immediately went to the app store to download it. This is the perfect app for me. I am a very moody person. My moods change with the direction of the wind. I am constantly creating playlists, but get tired of them quickly. This works so easily and the selections are right on the money. My only complaint is that I did not find this app sooner!
