I say second-best, because we all know that the title track off Teenage Dream was a defining moment not just for this raven-haired hooker, but for pop in 2010 in general.
Anyway, the '80s geek cover art for the regular single goes along great with the one for the remixes, though this one's a bit more elaborate. And kudos to Katy putting decent added touches on the artwork for each cover.
"Last Friday Night" is produced by Dr. Luke and Max Martin. My guess is that this will be Perry's fifth #1 single in a row off the so-so Teenage Dream.
