What kind of music I listen to really depends on my mood. It could be dubstep (Excision, Teminite, PsoGnar, to name a few out of my current dub playlist), various forms of metal (anywhere from After Forever to Xandria, In Flames, you name it); some times even Happy Hardcore / Handsup.
Generally, if I'm feeling well I prefer high BPM happy sounds, which -- together with some caffeinated drinks -- makes me incredibly productive. The darker my mood, the darker my taste of music gets, with also a few slower sounds. I can't really put numbers on my performance here, as on those days I prefer work that isn't easily evaluated performance-wise.
Nowadays I wear in-ear monitoring on stage which helps quite a lot, protection-wise. I've recently read about a study (dunno if it was on hn) where they discovered that vibrations behind the ear lessend the volume of the tinnitus. I am so going to try that if I ever get my hands on such a device.
I still have a very good hearing overall (especially in the base region), so I should not complain.
