Does anyone know of a case where a music wire spring failed due to hydrogen embrittlement?

Pearlitic microstructures are not immune to the effects of hydrogen. They are more resistant to brittle fracture than martensitic microstructures, but they are affected, usually by hydrogen-enhanced decohesion/delamination of the pearlite lamellae. There are a number of good references on the subject, such as the following:
