There are different types of digital partners who can help you get your music on the iTunes Store:
Aggregators help you format, deliver, and manage your music on the iTunes Store. They can also get Universal Product Codes (UPC) and International Standard Recording Codes (ISRC) for your music. If you sell any music, we will pay the aggregator directly, and the aggregator then pays you.
Encoding houses help you format and deliver your music, music videos, or concert films. If you sell any music, we will pay you directly.
