For a while there, it was Einsturzende Neubauten, "Sabrina" from Silence is Sexy, mostly because that first bass gank goes down pretty low, and I am familiar with it, and bass is pretty important to me. For mids and trebles, it's a track from Camille's Le Fil, and then it's usually Talk Talk's "The Rainbow" and "Desire", from Spirit of Eden for pretty much everything else (busy section, trumpet, black backgrounds, psychedelic section).
