Selling your music on iTunes is a big step for any indie artist. Essentially, you are choosing to step out of the realm of musicians who do nothing more than offer up their music for free via free music uploading sites and you’re choosing to ask people to buy your records.
First, you’ll have to learn how to sell your music online. Selling music on iTunes will lead you to signing your first distribution contract with a music distribution company (like ADED.US Music Distribution). Apple refers to these types of companies as aggregators and they are essentially the gate keepers to the iTunes and Apple Music world.
Making sure your music is in the proper format
Your music files
Apple only accepts high quality (lossless) files such as wav, flac, and ALAC (Apple lossless), and AIFF.
Your album cover art
Your album cover must be an exact square, meaning that the height and width of the image must be equal. It must be 3000 x 3000 pixels in size exactly and have a resolution of 300 dpi/ppi. Stores will not accept any release that doesn’t have the supplied album cover art
