Hello, and welcome to Just Answer.
My name is XXXXX XXXXX I have been an Entertainment Expert on Just Answer for 6 years. It's my pleasure to help you today.
The music you are referring to in that club scene with Mike Meyers and Paris Hilton is definitely not
"Getting Better". The music is definitely a 'generic' techno beat, most likely produced for that very short scene, and does not appear by name, in the soundtrack listing. If you enjoy that type of music, I can provide you with many places online to download it.
The song "Hang On" by Smash Mouth, is included in the movie, but definitely is not the music in the club scene you are asking about.
If you would like to view that particular scene in the underground club, it occurs at approximately 55 minutes into the movie. I own the movie and just watched the scene to listen to the music. It's is generic techno/club/dance music.
Smash Mouth did do a music video of the song "Hang On" including snippets of scenes from the movie "The Cat In The Hat", and Mike Meyers and Paris Hilton's club scene was included for about 2 seconds of it. You can view it here: http://www.youtube.com/watch?v=MmqGavhqwtA
You can view most of the club scene with Paris Hilton and Mike Meyers online, at this link, at 4 minutes and 43 seconds:http://www.dailymotion.com/video/xikozp_top-10-weirdest-the-cat-in-the-hat-moments_shortfilms
