You'll Know It's Us
From TowersStreet Wiki
The theme park audio market seems to be dominated by the company IMAscore, who have composed music for many different rides in a large portfolio of theme parks. Many of their tracks have similar elements, and you'll often hear enthusiasts saying 'ooh this sounds very Toverland!' Stemming from the similarity between many of their tracks, the phrase 'IMAscore: You'll know it's us!' came about.
