Mass Effect 2's soundtrack is pretty great, but you know what makes it better? Fan-made Hip-hop tracks devoted entirely to that most badass of pursuits: scanning a planet for minerals.
This is "Those Minerals", by Kabuto the Python, available for free on community music site Tindeck. Depending on your tastes, the rapping may be a little...hard on the ears, so if you'd prefer an instrumental version (beats by TH89, and viewable below), you can grab it from here.
