Too bad that it uses a proprietary code.

And that you spend more time configuring it, than actually playing music. :)

Actually it takes next to no time to configure. :)

Actually it takes next to no time to configure.

Yeah, its usable by default.

But it has endless possibilities of configuration (which is not a bad thing), and I hear people (tend to) spend a lot of time configuring it.

Though that's by their own choice. You can setup some nice appearances with a few clicks.
