Downloading not-so open source software

Ubuntu only comes with completely free and open source software. Stuff like mp3 playback and True Type fonts don't fall under that category, so in order to download that stuff using the automatic package manager (which is quite nice by the way), I have to enable additional "software sources". There is a Software Sources control panel. There are two additional check boxes that need to be selected, "Community maintained Open Source software" and "Software restricted by copyright or legal issues".

There are two easy ways to install these types of software, Automatix2 and EasyUbuntu. Automatix does more installations, but Easy Ubuntu concentrates on codecs and file types rather than software. Automatix does everything that Easy Ubuntu does, so I chose that one. I'm pretty sure they work the same.
