I really can't believe no one in the studio has been like "alright guys, we might be overdoing it with the na na na's" yet lol...
I think the song's alright and enjoyable for what it is, definitely think the bridge kicks ass, and then leading into the softer mark vocals as the drums kick back in has to be the best part of the song.
the parking lot part reminds me of that pave paradise put up a parking lot song
