Songza is a popular website that allows you to listen to almost any song instantly. Most of the songs are MP3 files, but there doesn't seem to be a way to download them. Some of the results are youtube videos, but the videos are invisible, only the music plays. Let's fix that.

Prefixed Portage

Most Linux distributions have great package managers like apt or portage. But installing programs when you don't have root access can be a pain. You need to find, download and install all the dependencies and their dependencies, setup a prefix somewhere in your home folder and hope that everything works.

Prefixed portage is perfect for those kinds of situations. It's a modified version of portage, the package manager of the Gentoo distribution. I am using it on a computer running Linux, but you can also use it on OS X, FreeBSD and Solaris to install applications and libraries from the portage repository.
