Mostly I listen to Metallica (S&M), when I do the hardcore scripting it's mostly "Battery" on repeat \:\)
Guns N' Roses is an altime favorite (Yeah I'm a GNR nut, got over 200 live concerts).
Tool, Filter, Testament, The Doors, Steppenwolf, The Eagles, Stevie Ray Vaughn, The Beatles (the r00t of everything), Jimi of course for some relaxed coding, and many others \:\)
