Lyrics (from LyricWiki.org):

You change your mind
Like a girl changes clothes
Yeah you, PMS
Like a bitch, I would know

And you over think
Always speak cryptically
I should know
That you're no good for me

Reviews:

More Hot than Cold Katy Perry is this year's breakout girl (in my opinion). This song is great and leaves you feeling more Hot than Cold!

Shaina MacMath Love it. Katy Perry is new and fresh. Love her voice and her songs so far.

Great song Great follow up as her second single from that album. Climbing the charts daily, has a great beat.

Had to get I hear this song all the time on the radio and it is very catchy and makes you want to turn your radio up.

Hot & Cold is Hot! This hot single is a great bouncy beat, with Katy singing over it in her unique voice. If you don't mind some foul words, you'll find a fun track. Katy Perry should stick to these more upbeat tracks. Her slower ones reveal her vocal weaknesses. Here, they are not apparent, which is all the better.
