Musical Coincidence

So I was listening to The Birthday Massacre's Pins and Needles album again*, and I noticed: the chorus for "Midnight" has the same melody as the chorus for "Deliver Me", by the David Crowly band (but I heard Sarah Brightman's cover first).

As far as I know, this is not parody, tribute, or plagiarism, simply different people at different times thinking "hey, this is a nice bit of melody", and doing very different things with it.  Have you ever encountered this phenomenon, gentle reader?


*My uncontested favorite from Pins and Needles is "Shallow Grave."
