First of all, don’t put your music on iTunes. It is vitally important for you to understand why it’s so important to own your relationship with your fans. There’s two big reason why you shouldn’t put your music on iTunes. The first is that they take a 30% cut off of whatever you sell on their platform. Not cool at all considering the fact that you don’t need them to host your projects.
The second thing is that they keep your fans data and refuse to give it out due to their “private policy”. So by selling your music through them, they basically become the gate keepers of your fan data. iTunes are building a monster database of everybody who’s buying music via their store. You need to be the one collecting fan information, they are YOUR fans not iTunes fans.
