I used to suffer from tinnitus myself, listening to loud rock music alot haha. AC/DC was the main culprit - love their music but their guitar sound, awesome as it is, is just too much for my ears. I can listen to any other band and no problems, but their guitar sound seems to always cause this nasty ringing in my ears...this used to a problem for years.
Now I don't have tinnitus anymore, mainly because I don't listen too AC/DC anymore (at least, not with headphones on lol), and generally just turning the volume down as much as possible
