Ill have whatever suits me at the time. Today feels like a 80s hair metal kinda day. Last week it was a Tossers/DKM Irish drinking music mood. Pandora is a beautiful thing.
I listen to the same music that I listen to when I do biochem work in lab, keeps me in the right mindset for culturing yeast and making media (in this case wort). Usually stuff like modest mouse, fugazi, pixies, and the sort keep things going
