The sales report is broken down into three sections, where you can view your sales and earnings organised by release, by store and by country. You can also filter this in the top by using the dropdown menus.
You will see your number of streams, how much you are paid per stream, the total earnings from streams, and then also the number of downloads and download earnings. Some services, such as Apple Music will have streaming and download revenue as the platform allows audiences to do both. As an example you will not see download earnings from Spotify as they are a stream only service, and you will never receive streaming revenue from iTunes, who are download only.
