Maloja gets rid of all the deadweight like a social network or event management. It only keeps track of your listening history and creates statistics from it. That's it. But this focus on its core does allow it to potentially implement much better database features. One example: Maloja supports multiple artists per track. So those poor artists who are always just mentioned as "featuring" in the track title can finally fight for a place in your personal charts.
I like to name my projects after regions in Grisons, Switzerland. Don't waste your time trying to find a connection, I just picked one at random. Do visit Maloja though. It's a great pass to drive.
