Electronica song plays on stereo but doesn't appear in list

There's a song that keeps playing on my Sims' stereo (they were listening to the Electronica station) that I liked a lot. I went to look it up in Game Options > Music but after listening to all the Electronica songs I still did not run across it. I have the City Living and Get Famous expansion packs and the Luxury Party stuff pack. Checked the song lists for those and the main game on the internet but still can't find it.

The song is kind of mellow with soft female vocals.
