Can't blame you.

"Radio-reception. A 35 year old Vietnam combat, veteran (32) started
to complain of depression, headaches, and hearing blurred voices and
music. Skull X-rays showed shrapnel metallic densities in the soft
tissues and cranial bones of the left parieto-occipital region. His
perception of voices and music were matched with stations in the AM
broadcast band, and consistently identified the same station in the
560 Khz range. His radio- reception involved the metal implant diode
rectification of the radio signal, and its bone transmission to the
auditory apparatus. Other cases of broadcast reception due to dental
work have been reported as well."

Any hope for future musical entertainment directly within the auditory
cortex?
