I have always listened to music when I code and it is common with many of the programmers I have worked with.
There is something about the way it turns off the outside world and lets me sink into the head space I need for code. My current top 10 coding albums are:
Death grips - No love deep web
Tool - Aenima
NIN - The fragile
Captain Beefheart - Trout mask replica (This is so out there)
Joy Division - Unknown Pleasures
Deftones - White Pony
Shitkid - Fish
Shabazz Palaces - Black up
Moodie Black - Nausea
Screaming Females - Ugly
As you can see, there is a sort of loud theme in there.
Do you code with music? What is your top 10?
I am always on the look for artists I have never heard :)
