Two of the demos were described in a cover story for Billboard, the first "a gorgeously sung, self-penned country ballad" and the second "a gobsmackingly awful trip-hop track" where Kesha raps ad lib for a minute when she runs out of lyrics near the end. Dr. Luke stated in an interview for the story that it was the latter track that caught his attention, saying "[w]hen you're listening to 100 CDs, that kind of bravado and chutzpah stand out."
Don't stop, make it pop
DJ, blow my speakers up
Tonight, I'mma fight
'Til we see the sunlight
Tick tock on the clock
But the party don't stop, no
The only possible explanation I have come up with so far is increasingly pervasive post-rationalist sensibilities, which eschew anything intelligent, sophisticated, or nuanced. Many people feel a separation between themselves and the purported elite, which could include highly-educated academics, scientific experts, classical musicians, theater actors, or anyone with a highly developed ability belonging traditionally to the upper or noble classes. Evidence can be found in Sarah Palin's popular idolization of "Joe the Plumber" or in the immense adult readership of children's' books such as the Harry Potter and Twilight series. In the above video, Kesha tries hard to replicate these anti-intellectual successes by having a large American flag on the stage and singing, "It only matters who I is." People listen because Kesha is basically the same as us, and her music sounds exactly like the music that we would make if we, too, were drunk and had no talent.
Some time after that, and after hearing a few of my friends excitedly include Lady Gaga songs on a mixtape (mix-iPod?), I came across a link that changed my opinion tremendously. The link led to a video---or a series of videos rather---showing that in addition to knowing her way around Top 40 charts, stages, and haute couture, Lady Gaga can tone it all down and produce something beautiful from raw talent alone. No recording, no post-production, and no one in the room except Lady Gaga and her keyboard. Having his much talent in its various forms is rare, especially among pop stars.
