According to three different sources, Viacom is paying a whopping $10 million for the rights to the music before the game even sells a single copy, and if it sells as expected, that number will go higher than $40 million. That’s not the game’s development cost. That’s just for licensing

so if you are more succesful you pay more?

Damn beatles, stop leeching on peoples wallets.
