For the Sims 2 any expansion DLCs soundtrack cannot compare to Nightlife, NL is probably the only CAS song list to ever make me hyped to enter build/CAS mode until some of the songs from Junkie XL play. His songs have been consistently great since NFS High Stakes, and Nightlifes soundtrack is no exception, special shoutout to OFB for the neighbourhood music though.
For the Sims 1, the only option other than the basegame would be Superstar since I just don't live in Magic Town enough to ever actually hear the buy/build music. Which does sound nice though...
Special shoutout to *this* masterpiece from On Holiday/Vacation though for how people ruined how I can hear the Simlish lyrics.

Sims 3 added music in expansions though? I don't remember too well.
