Back in March, Apple reached a deal with Dubset to make sure sampled artists in remixes and DJ mixes on its music service were properly compensated. Last week, Spotify did the same, inking an agreement to leverage Dubset's MixBANK distribution platform to ensure that both the artists creating the mixes and those being sampled receive the royalties they're due. The MixBANK system checks an uploaded track for copyrighted material before getting permission for its use from the correct label and/or publisher.
