The Sims 2 Pets Soundtrack (Windows, MacOS)

i don't want sound like an holy cow or anything i mean don't get me wrong the soundtrack is bitchin' but not all of it's there especially the one i've been looking for forever which was a pop song that i can't remember the name of because i lost the game. anyway other than that as i previoslly stated this is a badass OST.
There was a little tune when you went to the Town Square and you bought a pet or something. I love that song and I was wondering if it is on the soundtrack listing?
