The LFN snub by y'all.
Not the very song that pushed Katheryn to the "Female MJ" status.
Seriously though, the only reason why it feels like LFN didn't have that much impact was because it was vastly overshadowed by Party Rock Anthem, but it reigned Pop Songs for what felt like eternity before Moves Like Jagger (I think) came along.
I think people would still bop to it if they heard it on the radio, but it's not something that they would go out of their way to listen to, but that also goes for most hits during the 2009-2011 era. Still remains my favorite track from Teenage Dream tho.
can we get an update already. you think he'll get #1 next week?
