iPhone developer Tapulous has now sold more than five million songs through the in-game music store for its Tap Tap Revenge games.
What's more, every week the store's featured track - which is made available for free - is racking up more than 500,000 downloads from players.
The news comes as Tapulous announces a licensing deal with major label Warner Music Group to make four new premium games based on its artists in the next year.
