I just compared the top 30 songs on this list to the most recent top 30 on KIIS' playlist (per R&R). Of the top 30, KIIS and AMP share 22 songs. The 8 songs in AMP's top 30 but not in KIIS' top 30:
Nicola Fasano vs. Pat Rich, "75 Brazil Street"
Jamie Foxx w/ T-Pain, "Blame It"
Asher Roth, "I Love College"
Kanye West, "Paranoid"
T.I., "Whatever You Like"
Timbaland w/ One Republic, "Apologize"
Rihanna, "Disturbia"
Metro Station, "Shake It"
The 8 songs in KIIS' top 30 but not in AMP's top 30:
Black Eyed Peas, "Boom Boom Pow"
Ne-Yo, "Mad"
Pitbull, "I Know You Want Me"
Beyonce, "Halo"
A.R. Rahman, Pussycat Dolls, Nicole Scherzinger, "Jai Ho!"
Colby O'Donis f/ Akon, "What You Got"
Usher f/ Young Jeezy, "Love In This Club"
Ne-Yo, "Closer"
Not sure yet what to make of these differences. Is one more Rhythmic, more Rock, or more Adult than the other? Hard to say....
