This disclosure describes techniques and systems for enabling accessory devices to output supplemental content that is complementary to content output by a primary user device in situations where a separate music-provider system provides the primary content to the primary device. The techniques may include attempting to identify the primary content using metadata provided by the music-provider system, retrieving existing audio feature data in response to identifying the primary content, and providing the audio feature data to the accessory device for use in outputting the supplemental content. If the primary content is unable to be identified using metadata, then the techniques may include instructing the primary device to generate audio feature data and/or instructing the primary device to generate a fingerprint of the primary content for use in identifying the primary content.
