What kind of music was it?
Two words: magnets.
Some older and crappier speakers can actually pick up radio, it should be a little quieter/muffled than normal.
This used to happen to my old speakers from time to time, it always used to pick up some French or Belgian radio station, and was very quiet so I could barely make out even the foreign words, it was quite eerie.
