You guys need an external hard-drive. I have a 100GB USB external Seagate. If I download an album and I like it, or if a band I like releases something it gets put on, everything else that is not worth keeping get's deleted. I need to get a bigger one, though; lately I have been removing shit to make room for more. I keep movies on it as well. I've reformatted my local HD a few times since owning it. Perfect failsafe.
