Fraud: lying in the inducement or fulfilment of a contract.

If lying to induce or fulfil a contract were not a crime, someone could sell you a car telling you it has 0km, but it's actually 300km. Or they could sell you a hamburger telling you its made of meat, and it's actually made of soy. Etc..

Selling a song with 100M listens is a lie if you faked those 100M listens, it's not very different from stealing (but it is different)
