So after some thought I have changed my opinion on this. I fear that it will become clogged with forbidden artists like Muse, Led Zep, and Floyd, and not give artists that are actually available a chance to appear on the list.
Of course, the flip side of this is what if these artists being so consistently on the list somehow serve to change their minds about being on Rock Band? Quite honestly I don't see that happening. Random people on Facebook somehow bringing Axl and Slash together again? Not likely.
Also, Question: How does the voting work long-term? Do we get more points every week or month? Or are my ten votes going to be my only votes ever? That is going to skew the results a bit since I imagine most people won't vote for more than their absolute most wanted band with all ten.
