Hi Wild Coyote. I had a period of about one year when I had musical hallucinations. I heard music regardless of whether fans or AC were on, though I will admit they sometimes intensified with them on, or any electronic devise (i.e. the microwave). I had them more often when I was home than outside the house, but then again I was almost always home, unless I was at my therapist's or psychiatrist's office. When they first started, they were only a couple times per day, and not every day. At that time, I only heard original music, mostly classical music, then it became other types, like jazz, choral, and even Indian pow wow music. Later down the line, the frequency increased to several times per day, every day. It switched into what I called DJ voices on the radio, but not clear voices. More muffled. Sometimes it was one voice, and other times it was like a conversation.

I was quite disturbed by the musical hallucinations, especially when they continued beyond the first week. I remember telling my therapist about them and he made an obnoxious comment. At that time, it was the original music. He said "Wow! You should start writing the music down. You could make money from them." Not helpful! Luckily, my psychiatrist took my musical hallucinations much more seriously. [Long story. I'll spare you the rest. Anyone interested can read more about my experience at A Story of Musical Hallucinations (When music mostly died for me) – Bird Flight. So you know, my Tegretol XR (carbamazepine ER) seemed to be the "cure" for them.]
