Wow yeah it looks like you've got a ton of very high space-taking-up stuff. No wonder. Luckily my laptop of about 670 GBs of HD space doesn't use much of it generally. Around a gig of music, a few programs I use, then it's all games, DLed LP videos (other peoples' that I repeastedly enjoy), the final edits of my own, and raw files for future recordings. A lot of my games aren't too large in the size department either.
