"Dirty Diana" has a bit of a hair metal edge (with Billy Idol guitarist Steve Stevens), OK song though MJ had better like "Smooth Criminal"

"Make It Real" is another great ballad from 1988 and probably the best from The Jets (whom were around Deb's age)
"Together Forever" is an OK song
Never heard of "The Valley Road"
Prince had better songs than "Alphabet St."
"The Flame" and "Mercedes Boy" are both good song
"Kiss Me Deadly"... eh, I kinda find it cheesy, though catchy
"Pour Some Sugar On Me" from Def Leppard... Classic

Not familiar with songs 18 & 20. Heck, I didn't even know Hall & Oates were still putting out hits towards the end of the decade.
OK, as for now... I like Natasha Bedingfield, Duffy's "Mercy" , and The Ting Tings are OK. And that's basically it.
