Which game has the best soundtrack?

I'm only familiar with the music of TS1 & TS2, because at some point I began listening to my music + podcasts while Simming, so the only music I hear in TS4 is the emotion stings. I like TS1's neighborhood + build/buy mode music, and TS2's radio stations.

While Sims 2 is my favorite, I actually listen to all of them when I'm building. I have an iTunes playlist with allllllll the music from allllll the games. Took me a long time to collect it all.

It's really hard to be specific to a single pack/ep's soundtrack taking in account all 4 installments of the sims saga, I loved and disliked musical parts from all installments, to be precise I love TS4 main theme and TS3 theme, (an improved cover of TS2 University main theme) and also like TS2's one, about what's the best or the worst, it's up to any single user's taste, what is the best fo you, can be the worst for me, and viceversa.

About radio stations, in TS2 I avoided stations like techno, hip hop or pop, instead I sticked to Salsa, Heavy metal and classical ones, but they were too repetitive until I found the way to customize them, also I loved the latin radio from TS1 with all those Brazilian influenced tunes, There are too much "great" and too much "not so good" sounds in all installments and their packs, and it makes difficult to select one, but if I'm forced to choose one specific and global OST for an EP, I'd say it's "The Sims Hot Date" soundtrack. (Loves all that Jazz) ;)
