From the list:
The 5 Royales - Never heard of, seem to be this years token 50's band.
Black Sabbath - Should be there, their music has stood the test of time.
Jackson Browne - As a musician or for writing. IIRC he co-wrote some Eagles classics like Running on Empty and was on the Simpsons (not sure if that is a plus anymore). Musically, had a good run for about 10 years. Positive, recorded live from Merriweather, negative, almost caused the collapse of College Park concerts (SEE Productions) with his show there.
The Dells - Another 50s group that has been forgotten.
George Harrison - As a soloist I guess he did some big stuff in the early 70s, but really not that much, if he didn't die recently and wasn't a Beatle first I doubt he would have made it. Remember he is already in as a Beatle.
Lynyrd Skynyrd - They should be there, not my music, but heck they have a genre that they helped create.
John Cougar Mellencamp - I don't really think he belongs. If he makes it why not every other pop thing (e.g. Brian Adams).
The O'Jays - Disco sucks.
Gram Parsons - As a musician or producer? As the latter I would be for it as the former, not really.
Prince - Of course. He has done so much, and is the only real competition to Michael Jackson in the quirkiness field.
Bob Seger - Bleh. I guess my problem is that his music has not aged well, sure it was popular back in the 70s but so what, other than Chevy commercials what has survived of his legacy?
The Sex Pistols - Glen Matlock was at the Hall of Fame this summer for something so why not. They deserve to be there, as their is already a display that is almost all them at the place.
Patti Smith - On the fence here. Maybe she should maybe not. Has some great songs, was big in the punk movement, and still can kick it out. Would rather it be the whole group as Lenny Kay is the man.
The Stooges - Should be there.
Traffic - Another act whose music has faded. Really see them as just another band.
ZZ Top - They should be there. They rock, they have a unique sound that is very recognized, and they like hot rods.
Been to the museum once, and what amazes me is how some of these artists above have big displays already, so what does the induction do above that?
