Just like in the physical world, there can't be more than one distributor bringing the same album and/or video to the same music service. Most of the professional digital distribution companies, like EPM Music, work with the same music services. Having more than one digital distributor can create problems when two different distributors are delivering the same album to a certain music service. The music service will and can only pay out one distributor, not both of them. Most music services will not accept content from labels with more than one digital distributor and music services generally make sure that there are no cross deliveries.
