Spotify and Deezer have just released some awesome (not all) Scores from The Sims 4 that you can listen for free!
Please note that Spotify is not available for all countries, so you might want to play this Soundtrack from Deezer instead.

Find this a bit annoying, really. I paid extra for this soundtrack and now everyone gets to listen to it.
Sounds a bit selfish on my part but meh. XD
