This is a fun song with a cool beat and tempo. This is one that will be a favorite for a long time.

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

i find myself very disappointed in kate perry. her first song was good for its shock value and background music and that's what has made her popular i find no real value in her voice or lyrics and feel without the band she would be nothing. save your money for someone with talent like beounce.people made fun of brittney spears for her apperance at the mtv awards show but she still looked better than this woman with no kids. vocally speaking spears has more talent in her pinky than this woman has in her whole body and that's hard for me to say since i hate brittney spears!!i said it before i'll say it again if it wasn't for the band we wouldn't know this woman's name

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