Could we be getting items from this Pass The Spark Trailer?

I guess we now know what they recorded when someone spotted sims graffiti over at a movie studio.

I'm not sure if we could get new content, this seems to be very much focused on creators, maybe we will get some content from these creators. They are mentioning Sims Sessions and that it will include a backstage pass for people to look at how they record their songs in Simlish, they will probably add those songs to the game.
