Metallica Pro is a fun pin, but when my 11 year old plays it and immediately notices that "Mystery" is always 500K and asks me about it, you know the code is incomplete! 
That is just one of the items that is obviously left unfinished. I still have a blast playing it, and it will get much better when the code is updated for all of the missing features.
If you feel comfortable doing a little work on your pin, you can add the missing Spinners, they are not that expensive for the parts needed. I wired them up for scoring and sound and have it working per this thread:

IMHO, If your a fan of the band, you will enjoy the pin, even in its current state...
