Where is the option for neither?
Rock bands will satisfy pinheads, but each group/title will have its select fans. They are all going to be polarizing to some extent, but that has proven to not be a problem with sales for ACDC and Metallica, so it should not be a problem with most other big name groups.
I honestly would not mind seeing Stern do one rock band pin a year. I know I will not care much for half of the groups, but I am sure most of the games will have fun/decent gameplay.

But then the minority will likely be heard louder than they really are.

Is that what you plan on getting buried in? LOL

Says the guy that has ACDC and Metallica pins in his collection list.

I suggest trading them out for something else. I am sure somebody else could enjoy them and you could obviously enjoy something else. Who knows, maybe the next band pin will be the one that really clicks for you. There are only so many movie themes that will sell well in a given year, and I don't think it is realistic to think that Stern and JJP are going to be doing a bunch of non-licensed pins. It is simply too risky for them, but at least JJP is going to try with their 3rd title.

What a bunch of idiots.
