[T]he Rock Hall's future [is] as sketchy as a Detroit Avenue hooker on meth. The Hall's website claims that one of its goals is "to recognize the contributions of those who have had a significant impact on the evolution, development, and perpetuation of rock and roll." But how will it measure that? By record sales? Innovation? Will there be quotas for gender and race, as well as genres like hip-hop and techno? Or is it just one big popularity contest?

Scene called and asked, but Rock Hall spokeswoman Margaret Thresher didn't have a response. "Good question," she said.

The answer is that without a concrete definition of rock, there is no science to make the induction process flawless. Outside of Nirvana, the next decade doesn't boast many safe picks. Even Madonna will be a controversial inductee, seeing as the pop diva never released a rock record in her entire career.

Then there are the guys who sold out arenas, only to end up on the cheesy VH1 rock docs -- the Poisons and New Kids on the Blocks of the world. No one would claim they were innovative or had any staying power (NKOTB didn't even rawk!). But they defined musical eras and sold gobs 'n' gobs of records (even though they now make up 90 percent of the stock at the Record Exchange).

How will this shadowy induction committee weigh those guys against, say, the Replacements and Dinosaur Jr. -- artists that aren't household names and never graced the cover of Rolling Stone, but created whole new genres and birthed hundreds of new bands?

• Judas Priest - too scary
• Guns N' Roses - likely
• Captain Beefheart - too "out-there", but deserving
• Sting - too schmaltzy
• Black Flag - deserving, but too atonal
• Alanis Morissette - influential, but in a bad way
• Dr. Dre - probably with N.W.A., but not solo
• John Mayer - watered down Clapton
• Kraftwerk - should be in, but too German?
• Babyface - the 1990s' Phil Spector

As expected, the Nominating Committee contains a selection of rock critics and historians, music industry insiders, current and former Rolling Stone writers, and a few musicians. What is perhaps noteworthy about the list is that four of the 32 members come from a strong hip hop background (Grandmaster Flash & the Furious Five became the first ever rap group inducted into the Rock Hall in 2007). And if that weren't evidence enough that the Rock Hall has officially opened its doors to rap, Jay-Z is on the Rock Hall Board of Directors.

Notable for his absence from the list is Rolling Stone editor and publisher Jann Wenner, who is the Chairman of the Rock and Roll Hall of Fame Foundation.
