Calliope Sounds

I had a weird moment today. I was walking alone by the highway and heard calliope music. I instantly reached for my cell phone. This was weird because I don't use the sound as a ring-tone but my mind said "cell phone" and "alone" so it must be "mine". The music came from an ice cream truck on the highway. Seems like ring-tones have absorbed all the odd or misplaced musical sounds.
