When I first heard about Tangerine! from Potion Factory, my first thought was along the lines of “big deal. I can make my own playlists, thank you very much.” Since then, I decided to actually try it, and see if it really works.

It does.

My song library isn’t huge, but it’s good sized - just over 5400 songs. And Tangerine took just 30 minutes to analyze the whole library - with the exception of 300 or so ITMS purchases - on my PowerMac Dual 2.0 GHz G5.

So what is Tangerine!?

From the site:

Tangerine lets you easily create playlists with upbeat music, or playlists for relaxing. It does that by analyzing the BPM and beat intensity of the songs in your iTunes library.

Once it finished analyzing my library, it was pretty simple to create playlists based on the speed of the song. It even helped me create some good playlists for working out or working in the garage, that included songs I forgot I even had. It’s not perfect though, as there were a few songs that didn’t exactly have the correct tempo assigned to them, but still, this thing blows the doors off of manually entering in the tempo information for each song individually.

Tangerine! is for Tiger users only, and the UI looks great. It uses a UI nearly identical to iTunes for browsing your music, so you’ll immediately be able to find your way around. The rest of the app is very easy to use, and intuitive. I didn’t need to look for an instruction manual once.

Tangerine is currently in beta, so it’s free for the time being, and as a beta, it may very well still have bugs. But check it out, and see what you think.
