This number keeps calling me and leaving messages all hours of the night and day.  There's nobody there, just elevator music.  Really weird and kinda creepy.  I'd really like to know what it is.

Same as above.  Calls and plays weird midi music.  Please respond if you have answers.

Same here....called at 10:05AM PST. Bizarre creepy music.
Melissa Data free lookups says it's a Verizon Land Line in Kirkland, WA. Not ready to pay $35 to find out who it is, but I will try to investigate more.

1:55 am, left a two-second message of the weird music. Not cute.

425-727-6939

Called at 3:30 AM on a weekday. Left a voicemail with on hold music. Tried calling back 3 times on 2 different phones but it just rang once and then dead air. Not even a disconnect tone. Only if someone died calls come at that time of hour. So unhappy about that.
