Mobile games and music
Q: I have formed a company of programmers and developers to develop mobile games and applications. There are three sources of revenue:
1. Sell the game.
2. Make it free and gain revenue from advertisements in the applications and games.
3. Keep it partly free and partly under sale (in app purchases).
I have ensured that my apps and games will not contain anything vulgar or shameless. However, they will contain music. Is this permissible?
