Things I noticed about the radio edit:
-The instrumental is louder on the track, especially on the first verse.
-It seems like she re-recorded the bridge. There are bits that sound a little different. Like in some parts she sounds less enthusiastic.
-There are additional ad libs on the 3rd chorus.
-The echoing on the "bring the beat back" line.
I really like this song, which is weird cuz Katy usually doesn't work for me, but when the "it's no big deal" part comes on I struggle to not throw my headphones out of the window
