EVERYONE suffers from Tinnitus; just some people are more sensitive to it than others. My brother suffers from it badly at night, because he concentrates on it much more while sleeping.
It doesn't mean your medical is going to be bad but as a general rule you shouldn't have your music greater than 70% volume, if you hear any ringing after listening to music you should automatically stop and turn it down after giving your ears a break.
You do not want to continue any damage to your ears drums, my father suffers from Tinnitus so bad that he can't hear from his left ear, although this was a military injury many musicians and public speakers can suffer from it also.
If it gets any worse I would recommend speaking to your doctor.
