Here's a batch of all of Primary's releases I could find, as of February 2013. The only thing missing is the 2nd single, Fix. Most of the files are 320k mp3, except for a couple albums and the web singles. They also don't all have scans, because I was too lazy to find them all. I've included 4 web singles, all of which can be found on her site.
