Her songs that have been on the radio as far as I know are: Poker Face, Money Honey, Nothing Else I Can Say, The Fame. The Fame was even used on the intro to some top model show from America...but it was probably out dated since I was watching it in Australia and American shows seem to be heavily delayed before they're released on Aussie TV.
How could you forget "Just Dance", the anthem of every shallow drunken party girl in America? And I NEVER listen to the radio, I think I just heard that a few times in like fast food restaurants and stuff, and then tons of facebook photo albums with names like "I love this record baby but I can't see straight anymore"
I've got no problem admitting that I think her songs are awesome. Of course I know she's not writing the music itself (or probably the lyrics...) but she's got one heck of a voice and collaborates with the right musicians/writers.
It's not pretentious or emotionally constipated. It's just fun.
And as far as the original issue goes, I really hadn't assumed I'd ever have sex with her so I don't this as being a huge issue.
